The 4247 Model X03/Z03 Serial Matrix Printers

The 4247 Model X03/Z03 printers are professional, industrial impact-matrix printers. The 4247 Model X03/Z03 printers are rugged printers designed for harsh environments and demanding applications. Each of the 4247 models offers user-installable interface cards.

The 4247 Model X03/Z03 printers can have either one or two straight continuous-forms paper paths. One paper path is standard, and the second path is an optional feature. The printer operator panel is common with these models and includes the same full-function, full-size, 2 line by 24 character display, making messages and menus easy to understand.

Print-quality choices are Fast Draft mode (Model Z03 only), Data Processing mode (DP), DP Text mode (DP Text), and Near Letter Quality mode (NLQ). Versatile paper-handling capability provides printing on up to 8-part forms. Typical applications include transaction processing for invoices, office or internal business documents, as well as barcodes, labels, and multipart forms.

Printer description

The 4247 Model X03/Z03 printers build on the strengths of previous models of the 4247 family while providing a Fast Draft mode for the Model Z03 and a faster print speed for the Model X03.

Print speeds

The 4247 Model X03/Z03 printers print speeds (in characters per second):

Print Quality 4247 X03 4247 Z03

Fast Draft N/A 1100 Data Processing (DP) 800 800 DP Text 400 480 Near Letter Quality 200 240

Note: Print speed (CPS) at 10 CPI.

Paper paths

The 4247 Model X03/Z03 printers provide exceptional forms-handling flexibility. The base printer includes one front continuous-forms tractor paper path, and an optional second continuous-forms tractor paper path. Both continuous-form paper paths are front loading. Paper path linking is available when the optional second tractor is installed.

Paper path nomenclature

Front continuous-forms tractor: The first tractor visible when opening the front tractor cover is called the front continuous-forms tractor. In the standard (one tractor) configuration the installed tractor is called the front continuous-forms tractor.

In the optional (two tractor) configuration the forward most installed tractor is called the front continuous-forms tractor.

Rear continuous-forms tractor: In the optional (two tractor) configuration the tractor behind the front continuous-form tractor is called the rear continuous-forms tractor.

Print qualities

Fast Draft is a print quality available only for the 4247 Model Z03 printer. The Data Processing (DP), Data Processing Text (DP Text), Near Letter Quality (NLQ), OCR-A, and OCR-B print qualities on the 4247 Model X03 printer is equivalent in character size, shape, and resolution to the print qualities available on the 4247 Models Z03 printer.

Print quality selection

Print quality can be selected using program control or through the printer operator panel. Program control datastream commands take precedence over operator panel settings and can not be overridden.

Available printer operator panel settings are:

Print Quality = Fast Draft (Model Z03 printer) Fast Draft is the default setting for the Model Z03 printer.

Print Quality = DP

DP is the default setting for the Model X03 printer.

Print Quality = DP TEXT

Print Quality = NLQ

Print Quality = OCR-A

Print Quality = OCR-B

An 4247 Model Z03 printer operator panel feature, Host Fast Draft, is a setting that allows application programs written for earlier printers in DP mode to print in Fast Draft mode without changes to the application program. If Host Fast Draft is enabled then DP mode applications print in Fast Draft mode. If Host Fast Draft is disabled then DP mode applications print in DP mode.

The following table summarizes the print quality for Fast Draft (model Z03 only), DP, DP Text, and NLQ:

Horizontal character

Print quality Horizontal DPI Vertical DPI

Fast Draft 45 72 9 9 (Model Z03 only)

DP 60 72 12 9 DP Text 100 72 20 9 NLQ 100 144 20 18

xx Programmer Manual

Chapter 1. Personal Printer Data Stream (PPDS)

The 4247 Model X03/Z03 printers implement a subset of PPDS. The environment in which the printer data stream processor operates is described below.

Print Job Processing

There are no PPDS controls that explicitly define print job boundaries. A print job for the 4247 is established by the host system and consists of any set of related print objects. A print job could be as short as one character or could be many pages long.

As an aid to the printer operator, the printer provides a PROCESSING indicator on the operator panel. When the PROCESSING indicator is flashing, it indicates that data is currently being received, processed, or printing, or that data is buffered in the printer but cannot be immediately printed. If the PROCESSING indicator is not lit, then all print jobs have been completed.

Configuration parameter values can be changed at any time; however, to obtain predictable results, changes to operator panel configuration parameter values should be made before the print job is sent to the printer and after the previous print job has completed printing. Changing configuration parameter values while a print job is in progress may cause unpredictable results.

We recommend the following to ensure that your print jobs run correctly: v Establish a known print environment, and end any previous print job. Start each print job with a Set

Initial Conditions control. This control resets the printer environment to the default settings. You can then set additional controls depending on your print job environment.

v End each print job with a FORM FEED control. This control causes all data to be printed, and the

current position is set to the top-of-form position.

v If a print job is abnormally terminated, the job should be canceled. See “Cancel Print” in “Chapter 2.

Understanding the Operator Panel” in the User's Guide for your printer.

Page Printing Concept

The 4247 processes print jobs in terms of pages, as well as in lines and columns. A page is a logical entity whose boundaries are defined by the width and the page length. These boundaries are established during printer initialization using the printer defaults, and can be changed using the Configuration Menu or by issuing the appropriate data stream controls.

As a job prints, the printer controller maintains both the logical position and the physical position on the page. If a print job does not end with a proper job terminator (for example, FORM FEED), then:

v All data for the current page may not print v The next print job may be misaligned on the form v Residual data from a previous job could print with the new job.

Page Presentation

Many PPDS commands (tabs, margins, line spacing, for example) are described in terms of the presentation surface. A presentation surface is a two-dimensional surface upon which the printer positions symbols according to controls embedded in the incoming data stream. The presentation surface is defined in absolute terms by the width and depth parameters of the page size control commands (Set Page Length, Set Horizontal Margins, for example). The physical print position does not move outside the range of these two parameters. The left margin (LM) and right margin (RM) are variable parameters within the presentation surface. The logical print position does not move outside the range of the vertical margins nor outside the horizontal margins + 1. The following figure shows the presentation surface and the

1

relationships of some of these parameters.

CPP Current Print Position (LM ≤ CPP ≤ RM). CPL Current Print Line MPP Maximum Print Position (in characters at current CPI) PMPP Physical Maximum Print Position. The largest number of characters that can be placed on one line

of the surface (the largest value that MPP can assume).

LM Left Margin RM Right Margin MPL Maximum Page Length (in lines at current LPI)

Notes:

1. The host should set the limits of the presentation surface if the default or previous values are not acceptable.

2. The operator should align the physical paper so that it matches the logical presentation surface.

Also created with this surface is a pair of numbers (CPL and CPP) which specify the line number and column number where the next graphic will be printed. These internal values are the logical position on the presentation surface.

The variable parameters have default values which are established when the printer is initialized. The standard power-on defaults are:

MPP (width) Operator panel setting MPL (depth) Operator panel setting CPI Operator panel setting LPI Operator panel setting LM 0 inches (Column 1)

2 Programmer Manual

RM Equal to MPP HT Horizontal tabs are set at each 8th column, starting with column 9 (9, 17,

25, 33, and so on.)

VT Vertical tabs are all cleared

Graphic and Control Character Sequences

PPDS uses an ASCII encoding scheme to define controls and printable graphics. Multiple code pages for printable graphics are supported. Control characters are interpreted based on the environment established by any preceding control characters and signals.

The 4247 supports several ASCII code pages. Within a code page, a code point can be treated as a printable character (including space) or as a control code. The following data stream controls affect how a code point is interpreted:

ESC 6 Select PC Character Set 2 ESC 7 Select PC Character Set 1 ESC \ Print All Characters ESC ^ Print Single Character ESC[K

Set Initial Conditions

The following code points are interpreted as control characters: v PC Character Set 1

X'00' to X'1F' X'7F' (treated as NULL) X'80'' to X'9F'

v PC Character Set 2

X'00' to X'02' X'07' to X'1F' X'7F' (treated as NULL)

Note: No characters are treated as controls when they are part of a Print Single Character or Print All

Characters control.

The following code points are interpreted as printable graphic characters: v PC Character Set 1

X'20' (space) X'21' to X'7E' X'A0'' to X'FE' X'FF' (required space)

v PC Character Set 2

X'03' to X'06' X'20' (space) X'20' to X'7E' X'80' to X'FE' X'FF' (required space)

Note: All characters are treated as printable graphic characters when they are part of a Print Single

Character or Print All Characters control.

Chapter 1. Personal Printer Data Stream (PPDS) 3

PPDS Compatibility

PPDS is supported in 4247, 2381 Personal Printer, and 4202 Proprinter III XL emulation modes. When 4247 is selected, PPDS control codes are supported in the same manner as if emulating the 2381 Personal Printer. The Emulation Mode can be selected from the Configuration Menu using the operator panel. Emulation mode may also be selected using the Set Initial Conditions (ESC [ K) control sequence, if the printer is set to 4247 or 2381 Personal Printer emulation mode.

One-Byte Controls

The printer uses the following one-byte controls:

Control Hex Name

NUL 00 (80) Null (no operation) BEL 07 (87) Bell BS 08 (88) Backspace HT 09 (89) Horizontal Tab LF 0A (8A) Line Feed VT 0B (8B) Vertical Tab FF 0C (8C) Form Feed CR 0D (8D) Carriage Return SO 0E (8E) Shift Out (Double-Wide Print) SI 0F (8F) Shift In (Condensed Print) DC1 11 (91) Device Control 1 (Select) DC2 12 (92) Device Control 2 (Select 10 CPI) DC3 13 (93) Device Control 3 (Deselect) DC4 14 (94) Device Control 4 (Cancel Double-Wide Print) CAN 18 (98) Cancel ESC 1B (99) Escape (Multiple-byte control prefix) SP 20 Space

Note: Control hex values within parentheses (nn) are recognized only within PC Character Set 1.

Null (NUL)

00

This control terminates the Set Horizontal Tab and Set Vertical Tab control codes. The printer ignores NUL by itself.

Bell (BEL)

07

This control causes the audible alarm to sound, if enabled. The alarm may be disabled or enabled from the Configuration Menu.

4 Programmer Manual

Backspace (BS)

08

This control moves the print position horizontally one character width to the left. If the current print position is at the left margin, the printer ignores this command.

Horizontal Tab (HT)

09

This control moves the print position to the next horizontal tab stop. If there are no tab stops to the right, or if the next tab stop is beyond the current right margin, the control is ignored.

Line Feed (LF)

0A

This control advances the paper one line. The horizontal position does not change unless automatic carriage return mode is activated from the operator panel Configuration Menu. If the paper advance crosses the bottom margin, the printer completes all deferred printing on the current page and then does an automatic form feed.

If skip perforation mode is active and the bottom margin is crossed, the vertical position on the new page following the automatic form feed will be the top-of-form position. If skip perforation is not active, the vertical position on the new page is the point immediately following the previous print line.

Vertical Tab (VT)

0B

This control causes the vertical print position to be advanced to the next vertical tab stop. The horizontal position is not affected unless automatic carriage return mode is activated from the operator panel Configuration Menu. If there are no tab stops past the current vertical print position, Vertical Tab is treated as a Line Feed.

Form Feed (FF)

0C

This control causes a new page to be started. Form Feed is a line end and page end control; it causes all deferred printing that may have been buffered for the current page to be completed and the form physically advanced to eject the current page. The vertical print position advances to the top margin and the horizontal print position is set to the left margin for subsequent printing.

Carriage Return (CR)

0D

Chapter 1. Personal Printer Data Stream (PPDS) 5

This control moves the current horizontal print position to the left margin. The vertical print position does not change unless automatic line feed mode is active (see “Set Auto Line Feed (ESC 5)” on page 13).

Shift Out (SO) / Double-Wide Print

0E

This control causes the printer to start double-width printing. Double-width printing prints the characters twice as wide as the current character spacing. This results in half as many characters per inch. Each character takes up the space of two single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab, Double-Wide Continuous Mode, or Cancel Double-Wide Print with vertical movement specified cancels the Shift Out control code.

Shift In (SI) / Condensed Print

0F

This control prints graphic characters in condensed pitch (15 CPI, 16.7 CPI, 17.1 CPI or 20 CPI).

Shift In is a buffer terminating control; if printable data at a different character-per-inch setting is buffered, that data is printed before the setting is changed. The current print position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line, and this control changes the maximum number of characters that can be printed on one line.

When Printer Compatibility 7 – Condensed Print option in the ASCII Configuration menu is set to 15 CPI, then 15 CPI is selected, otherwise, 16.7 CPI or 17.1 CPI is selected.

A combination of 12 CPI and Condensed Print sets the printer to 20 CPI when Printer Compatibility 9 (20 CPI) option is set to Enabled in the ASCII Configuration menu. A combination of 12 CPI and Condensed Print sets the printer to 12 CPI when Printer Compatibility 9 (20 CPI) option is set to Disabled in the ASCII Configuration menu.

Device Control 1 (DC1) / Select

11

This control selects the printer.

Device Control 2 (DC2) / Select

12

This control sets 10 characters per inch. DC2 is a buffer terminating control; if printable data at a different characters-per-inch setting is buffered, that data is printed before the setting is changed. The current print position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 3 (DC3) / Select

13

6 Programmer Manual

This control is treated as a NUL.

Device Control 4 (DC4) / Select

14

This control cancels double-wide printing if double wide was selected with the Shift Out control. The characters-per-inch setting returns to the previous value.

Cancel (CAN)

18

This control purges all buffered data. All data received after the most recent buffer terminating control is discarded. For a list of buffer terminating controls, see “Buffer Terminating Conditions” on page 38. Any data received after Cancel is processed normally. Cancel does not change the current print position.

Escape (ESC)

1B

This control is a prefix used in combination with supplementary control bytes to provide an extended set of control functions.

Space

20

This control moves the print position one character space to the right.

Escape Sequence Controls

Escape sequence controls have an ESC followed by one or more control parameters. Supported escape sequence controls are:

1B 07

This control causes the audible alarm to sound, if enabled. The alarm may be disabled or enabled from the Configuration Menu.

Backspace (ESC BS)

1B 08

This control moves the print position horizontally one character width to the left. If the current print position is at the left margin, the printer ignores this command.

Horizontal Tab (ESC HT)

1B 09

This control moves the print position to the next horizontal tab stop. If there are no tab stops to the right, or if the next tab stop is beyond the current right margin, the control is ignored.

Line Feed (ESC LF)

1B 0A

Chapter 1. Personal Printer Data Stream (PPDS) 9

This control advances the paper one line. The horizontal position does not change unless automatic carriage return mode is activated from the operator panel Configuration Menu. If the paper advance crosses the bottom margin, the printer completes all deferred printing on the current page and then does an automatic form feed.

If skip perforation mode is active and the bottom margin is crossed, the vertical position on the new page following the automatic form feed will be the top-of-form position. If skip perforation is not active, the vertical position on the new page is the point immediately following the previous print line.

Vertical Tab (ESC VT)

1B 0B

This control causes the vertical print position to be advanced to the next vertical tab stop. The horizontal position is not affected unless automatic carriage return mode is activated from the operator panel Configuration Menu. If there are no tab stops past the current vertical print position, Vertical Tab is treated as a Line Feed.

Form Feed (ESC FF)

1B 0C

This control causes a new page to be started. Form Feed is a line end and page end control; it causes all deferred printing that may have been buffered for the current page to be completed and the form physically advanced to eject the current page. The vertical print position advances to the top margin and the horizontal print position is set to the left margin for subsequent printing.

Carriage Return (ESC CR)

1B 0D

This control moves the current horizontal print position to the left margin. The vertical print position does not change unless automatic line feed mode is active (see “Set Auto Line Feed (ESC 5)” on page 13).

Shift Out (ESC SO) / Doube-Wide Print

1B 0E

This control causes the printer to start double-width printing. Double-width printing prints the characters twice as wide as the current character spacing. This results in half as many characters per inch. Each character takes up the space of two single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab, Double-Wide Continuous Mode, or Cancel Double-Wide Print with vertical movement specified cancels the Shift Out control code.

Shift In (ESC SI) / Condensed Print

1B 0F

This control prints graphic characters in condensed pitch (15 CPI, 16.7 CPI, 17.1 CPI or 20 CPI).

10 Programmer Manual

Shift In is a buffer terminating control; if printable data at a different character-per-inch setting is buffered, that data is printed before the setting is changed. The current print position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line, and this control changes the maximum number of characters that can be printed on one line.

When Printer Compatibility 7 – Condensed Print option in the ASCII Configuration Menu is set to 15 CPI, then 15 CPI is selected, otherwise, 16.7 CPI or 17.1 CPI is selected.

A combination of 12 CPI and Condensed Print sets the printer to 20 CPI when Printer Compatibility 9 (20 CPI) option is set to Enabled in the ASCII Configuration menu. A combination of 12 CPI and Condensed Print sets the printer to 12 CPI when Printer Compatibility 9 (20 CPI) option is set to Disabled in the ASCII Configuration menu.

Device Control 1 (ESC DC1 / Select)

1B 11

This control selects the printer.

Device Control 2 (ESC DC2) / Select 10 CPI

1B 12

This control sets 10 characters per inch. DC2 is a buffer terminating control; if printable data at a different characters-per-inch setting is buffered, that data is printed before the setting is changed. The current print position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 3 (ESC DC3) / Deselect

1B 13

This control is treated as a NUL.

Device Control 4 (ESC DC4) / Cancel Double-Wide Print

1B 14

This control cancels double-wide printing if double wide was selected with the Shift Out control. The characters-per-inch setting returns to the previous value.

Cancel (ESC CAN)

1B 18

This control purges all data in the preceding print buffer. Any data received after Cancel is processed normally. Cancel does not change the current print position.

Chapter 1. Personal Printer Data Stream (PPDS) 11

Auto Underscore (ESC -)

1B 2D NN

This control turns on and off the continuous underscore function.

If NN is 1, the printer underscores all text characters and spaces following this sequence. The printer does not underscore white space caused by horizontal tabs.

If NN is 0, the printers stops the underscore of all data following this sequence.

Set 1/8 Inch Line Spacing (ESC 0)

1B 30

This control sets the line spacing to eight lines per inch.

The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 15.

Set 7/72 Inch Line Spacing (ESC 1)

1B 31

This control sets the line spacing to 7/72 inch. The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 15.

Invoke Text Line Spacing (ESC 2)

1B 32

This control sets the line spacing at the value set by the last Set Text Line Spacing (ESC A) control received. The printer sets the line spacing to six lines per inch if no ESC A has been issued.

Set Graphics Line Spacing (ESC 3)

1B 33 NN

This control changes the line spacing to the value specified by NN.

NN is a value that specifies the line spacing in units of 1/216 inch. Valid values are 0 to 255. If N equals 0, the printer ignores this control.

The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 15.

12 Programmer Manual

Set Top of Form (ESC 4)

1B 34

This control establishes the current vertical position as the top of form.

Set Auto Line Feed (ESC 5)

1B 35 NN

This control sets the automatic line feed mode of the printer. When automatic line feed is on, the printer does a line feed each time it receives a carriage return. When automatic line feed if off, a carriage return is processed normally. This control overrides the automatic line feed mode set in the operator panel Configuration Menu.

If NN is 1, the printer turns automatic line feed mode on.

If NN is 0, the printer turns automatic line feed mode off.

Select PC Character Set 2 (ESC 6)

1B 36

This control selects PC Character Set 2 as the active character set. In PC Character Set 2, code points X'03' to X'06', X'15', and X'80' to X'9F' are treated as graphic characters (not controls). See “Graphic and Control Character Sequences” on page 3.

Select PC Character Set 1 (ESC 7)

1B 37

This control selects PC Character Set 1. In PC Character Set 1, code pointsX'03' to X'06', X'15', and X'80' to X'9F' are treated as controls (not printable graphics). See “Graphic and Control Character Sequences” on page 3.

Set 12 CPI (ESC :)

1B 3A

This control sets the pitch to 12 characters per inch. If the current font is proportionally spaced, this control selects a horizontal resolution of 240 dots per inch. If the active font is OCR, the printer does not prohibit the change in pitch; however, the printed OCR characters may be unreadable by automatic identification equipment.

Unidirectional Printing (ESC <)

1B 3C

Chapter 1. Personal Printer Data Stream (PPDS) 13

This command selects unidirectional printing for one line only. The print head moves to the home position at the left side of the printer and prints one line, left to right. The command is then cancelled by the carriage return that sends the print head back to the home position.

Character Font Image Download (ESC =)

1B 3D LL HH FF LF W H CP N XX...XX

This control downloads special character images.

A two-byte count (LL HH) indicates the number of bytes that follow in this control.

LL is the least significant byte of the count; HH is the most significant byte of the count. The number of bytes that follow should equal HH × 256 + LL. If the count equals X'0000', the control is ignored.

FF is the format byte and must equal X'13'. LF is a one-byte font identifier that specifies the previously initialized or selected font to be modified. See “Change Font (ESC I)” on page 16.

W is a one-byte value that specifies the width of the character cells in options. For DP fonts, the value is X'0A'. For fixed pitch DP Text and NLQ fonts, the value is X'14'. For DP Text and NLQ, proportional fonts values may vary. However, for all code points downloaded with this control, all character cells defined will be Width options wide.

H is a one-byte value that specifies the height of the character cells in dots. Valid values are X'09' for DP and DP Text and X'12' for NLQ.

CP is a one-byte value. This parameter specifies the first code point to download. A single code point or multiple code points can be downloaded. If the font being downloaded was previously initialized, the downloaded characters overlay the resident characters in the font.

N is a one-byte value that specifies the number of code points defined by this control. If the starting code point plus the number of code points is greater than 256, the control is ignored.

XX .. XX is the font image download data. These data bytes define the character cells. Multiple bytes define each vertical slice of the character cell. The slice data for each code point is in a contiguous format (run-together) as follows:

v If the slice data is nine-bits high, byte 1 is put into the high-order bits in slice 1 and the high-order bit of

byte 2 is the low order bit of slice 1. The remaining seven bits of byte 2 are put into the high-order seven bits of slice 2, and so on.

v If the slice data is 18-bits high, bytes 1 and 2 are put into the high-order bits of the first slice and the

two high-order bits of byte 3 complete the first slice. Slice 2 is composed similarly, starting with the remaining six bits in byte 3.

Note: The contiguous format (run-together) does not occur from one code point to the next. The top dot of

the leftmost slice of each code point is always in the high-order bit of the first byte of image data for that code point.

The number of data bytes required to define the image for each code point can be calculated as follows:

Image Length = (Width × Height) ÷ 8

Note: If there is a remainder from the division by 8, add 1 to the quotient.

Example: To define an image for a standard DP font where Width = 10 and Height = 9:

Image Length = (10 × 9) ÷ 8

14 Programmer Manual

Image Length = 11 with a remainder of 2 Image Length = 12 bytes per character

If both printer provided images and downloaded images are to be printed from the same local font ID, we recommend that the downloaded images be sent, using this control, at the start of a print job when the print environment for the job is established. This ensures that the actual printed output appears as intended.

It is also recommended that image data bits for the last vertical column of NLQ character patterns be all zeros. The last vertical column will be clipped if NLQ character patterns are expanded for graphics printing. Resident NLQ text character patterns do not contain image data (dots) in the last column of the character box.

Select n/72 Inch Line Spacing (ESC A)

1B 41 NN

This control stores the line spacing value, in units of 1/72 inch, which is later selected by Invoke Text Line Spacing (ESC 2). The valid values for NN are X'01' to X'FF' (1 to 255). The default line spacing is X'0C' (six lines per inch).

A value of 0 is not valid and causes the printer to ignore this command. Following are example values for NN: X'00' No Change X'18' 3 LPI X'12' 4 LPI X'0C' 6 LPI X'09' 8 LPI X'08' 9 LPI X'06' 12 LPI

Set Vertical Tabs (ESC B)

1B 42 TT...TT 00

This control sets the vertical tab stops. The maximum number of tab stops supported is 64. The Null control code terminates this sequence. If the Null terminator is missing, the printer treats the next 64 bytes as tab stops and ignores all the data bytes following these 64 bytes until a Null is received. If the printer receives this sequence without any tabs specified, all tab stops are cleared.

TT...TT are the tab values that specify the tab stops as line numbers, relative to the top of the physical page. Tab stops must be specified in ascending order; entries not in ascending order are ignored.

Set Page Length (ESC C)

1B 43 LL IN

This control sets the physical page length in lines or inches and resets skip perforation mode.

LL is a one-byte hexadecimal number that specifies the page length in lines. The value is converted to inches based upon the current line spacing. Valid values for LL are X'01' to X'FF', but the resulting page length in inches must be less than 113.8 inches (2890 mm). If LL equals 0, then parameter II (length is inches) is used.

Chapter 1. Personal Printer Data Stream (PPDS) 15

IN is a one-byte hexadecimal number that specifies the page length in inches. IN is present only if parameter LL equals 0. Valid values for IN are X'01' to X'71'. If IN is greater than the maximum value, the maximum value is used. If both LL and IN are zero, the control is ignored.

Set Horizontal Tabs (ESC D)

1B 44 TT...TT 00

This control sets the horizontal tab stops. The maximum number of tab stops supported is 28. The sequence terminates with the NUL control code. If the null terminator is missing, the printer treats the next 28 bytes as tab stops and ignores all the data bytes following the 28 bytes until a Null is received. If the printer receives this control code with no tabs, all horizontal tab stops are cleared.

TT is the list of tab stops as character positions relative to the left edge of the physical page. Valid values are X'01' to X'FF'. Tab stops must be specified in ascending order. Entries not in ascending order are ignored.

Begin Emphasized Print (ESC E)

1B 45

This control starts emphasized print mode (bold style). Emphasized printing continues until the printer receives an End Emphasized Print (ESC F) control or the printer is initialized.

End Emphasized Print (ESC F)

1B 46

This control ends emphasized print mode (bold style).

Begin Double-Strike Print (ESC G)

1B 47

This control starts double-strike printing (all text characters are double struck). Double-strike printing continues until the printer receives an End Double-Strike Print control (ESC H) or the printer is initialized.

End Double-Strike Print (ESC H)

1B 48

This control ends double-strike printing.

Change Font (ESC I)

1B 49 NN

This control selects the font to be used for printing.

16 Programmer Manual

NN is the one-byte local font identifier number that specifies the font. The mapping of the local font identifier is dependent upon the printer's emulation mode setting. In the Configuration Menu, if the emulation mode is set to 4202 III XL, the Change Font control code selects fonts compatible with the 4202 Proprinter III XL Printer. If the emulation mode is set to 4247 or 2381, Change Font selects the fonts compatible with the 2381 Personal Printer.

Supported local font identifiers are shown in the following table.

Local Font Identifier (Hex) 4247 and 2381 Emulation Mode 4202 III XL Emulation Mode

00 Default (op. panel selection) DP 01 DP Fast Draft (for model Z03); DP (for model X03)

Notes:

1. If printer configuration Host Fast Draft setting is Enabled, then Fast Draft quality is selected. If Host Fast Draft is disabled then DP quality is selected (only for model Z03).

2. If a downloaded font has not been previously downloaded with a Character Font Image Download control (CFID), a Change Font control to select a downloaded font is ignored.

3. The NLQ font style is selected as defined in the Configuration Menu as either Courier or Gothic.

Relative Move Baseline (ESC J)

1B 4A NN

This control performs a vertical move relative to the current print position.

Chapter 1. Personal Printer Data Stream (PPDS) 17

NN is a one-byte hexadecimal value that specifies the move amount in units of 1/216 inch. The printer will adjust the value to the nearest 1/144 inch. If Automatic Carriage Return on Line Feed is set in the operator panel Configuration Menu, a carriage return is also performed when a Relative Move Baseline code is received (see “Carriage Return (CR)” on page 5).

Normal Density Bit Image Graphics (ESC K)

1B 4B LL HH NN...NN

This control prints the supplied bit image data at 60 horizontal pel by 72 vertical pel. Bit image data can be mixed with text data on the same line.

A two-byte count (LL HH) indicates the number of bytes that follow in this control. LL is the least significant byte of the count; HH is the most significant byte. (The number of bytes that follow should equal HH × 256 + LL.) If the count equals X'0000', the control is ignored.

NN...NN are the bytes containing the bit image data. The data format is in 8-bit vertical slices, with the least significant bit the bottom dot and the most significant bit the top dot. B'1' indicates a pel to be printed; B'0' indicates an un-printed pel. Data that exceeds the right margin is discarded.

Dual Density Bit Image Graphics Type 1 (ESC L)

1B 4C LL HH NN...NN

This control prints the supplied bit image data at 120 horizontal by 72 vertical pel. Bit image data can be mixed with text data on the same line.

A two-byte count (LL HH) indicates the number of bytes that follow in this control. LL is the least significant byte of the count; HH is the most significant byte. (The number of bytes that follow should equal HH × 256 + LL.) If the count equals X'0000', the control is ignored.

NN .. NN are the bytes containing the bit image data. The data format is in 8-bit vertical slices, with the least significant bit the bottom dot and the most significant bit the top dot. B'1' indicates a pel to be printed; B'0' indicates an un-printed pel. Data that exceeds the right margin is discarded.

Begin Skip Perforation (ESC N)

1B 4E NN

This control sets the number of lines to be skipped at the bottom of each page. Once this function is activated, it stays active until the End Skip Perforation (ESC O) or Set Page Length (ESC C) control is received or the printer is initialized.

NN is a one-byte hexadecimal value that specifies the number of lines to skip at the bottom of each page. This value must be zero or greater and less than the length of the page in lines (from 0 to 255). Once Begin Skip Perforation is activated, the number of lines that may be printed on a page is the page length minus NN.

End Skip Perforation (ESC O)

1B 4F

18 Programmer Manual

This control ends skip perforation.

Proportional Space Mode (ESC P)

1B 50 NN

This control starts or stops proportional space mode.

NN is a one-byte hexadecimal value that sets proportional space mode on or off.

v If NN is 1, proportional space mode is on. v If NN is 0, proportional space mode is off.

Note: Code pages OCR-A (code page 876), OCR-B (code page 877), Arabic (code page 864), Cyrillic

(code page 855), Thai (code page 874), Extended Arabic (code page 1046), and Farsi Bilingual (code page 1098) are not supported in proportional space mode.

Deselect on Positive Query Reply (ESC Q)

1B 51 NN

This control deselects the printer if the response to the query is positive.

NN is the query printer identifier. If the value matches the printer's ID, the query response is positive and the printer deactivates the Select line. If the query is not positive, the control is ignored.

The printer must be reselected using a DC1 control after a positive response to ESC Q if the printer is to be used.

Query Identifiers: If the emulation mode is set to 4202 III XL, the printer ID is X'16'. If the emulation mode is set to 4247 or 2381, the printer ID is X'B8'.

Set Default Tabs (ESC R)

1B 52

This control resets both the horizontal and vertical tab stops. The horizontal tab stops are set to every eighth position starting with the ninth column (9, 17, 25,...). The vertical tab stops are cleared.

Begin Subscript/Superscript (ESC S)

1B 53 NN

This control activates subscript and superscript printing. Once this printing is active, it stays active until another Begin Subscript/Superscript control changes the mode, an End Subscript/Superscript control is received, or the printer is initialized.

NN is a one-byte hexadecimal value that activates subscript or superscript printing.

v If NN is 1, subscript mode is active. v If NN is 0, superscript mode is active.

Chapter 1. Personal Printer Data Stream (PPDS) 19

End Subscript/Superscript (ESC T)

1B 54

v If NN is 1, unidirectional printing is selected. v If NN is 0, bidirectional printing (default) is selected.

Double-Wide Continuous Mode (ESC W)

1B 57 NN

This control turns double-wide printing on or off. When double-wide printing is on, the width of subsequent graphic characters is doubled (the characters per inch value is half of the single character value). For tabs, the font width is not doubled (tab distance is based upon single character width).

NN is a one-byte hexadecimal value that turns double-wide printing on or off.

v If NN is 1, double-wide printing is turned on. v If NN is 0, double-wide printing is turned off.

Note: Double-Wide Continuous Mode does the same function as Shift Out, except double wide printing is

not canceled when a new line begins.

Set Horizontal Margins (ESC X)

1B 58 LL RR

This control sets the left and right margins. The margins are specified in character positions relative to the left edge of the physical page.

LL is a one-byte hexadecimal value from X'00' to X'FF', which specifies the starting print position relative to the left edge of the physical page. If LL equals 0, the left margin is unchanged.

RR is a one-byte hexadecimal number from X'00' to X'FF' that specifies the rightmost print position relative to the first print position. If RR equals 0, the right margin is unchanged.

Notes:

1. Set Horizontal Margins should be followed by a carriage return (CR) control to set the print position to the new left margin.

2. LL should be at least one character width less than the page width.

3. If RR is greater than the page width or is less than LL, RR is set to the page width (MPP).

38 Programmer Manual

Chapter 2. Epson FX-1050 Data Stream

When the 4247 is in Epson emulation mode, the printer can print files coded for the Epson FX-1050 printer using the Epson ESC/P printer control language. Use the Configuration menu to select Epson FX emulation mode as the active printer configuration.

The following chapter describes the Epson FX-1050 emulation host control codes that are supported for the printer.

Print Job Processing

There are no Epson FX-1050 controls that explicitly define print job boundaries. A print job for the 4247 is established by the host system and consists of any set of related print objects. A print job could be as short as one character or could be many pages long.

As an aid to the printer operator, the printer provides a Processing indicator on the operator panel. When the Processing indicator is flashing, it indicates that data is currently being received, processed, or printing, or that data is buffered in the printer but cannot be immediately printed. If the Processing indicator is not lit, then all print jobs have been completed.

Configuration parameter values can be changed at any time; however, to obtain predictable results, changes to operator panel configuration parameter values should be made before the print job is sent to the printer and after the previous print job has completed printing. Changing configuration parameter values while a print job is in progress may cause unpredictable results.

We recommend the following to ensure that your print jobs run correctly: v Establish a known print environment, and end any previous print job. Start each print job with an

Initialize Printer/control. This control resets the printer environment to the default settings. You can then set additional controls depending on your print job environment.

v End each print job with a Form Feed control. This control causes all data to be printed, and the current

position is set to the top-of-form position.

v If a print job is abnormally terminated, the job should be canceled. See “Cancel Print” in “Chapter 2.

Understanding the Operator Panel” in the User's Guide for your printer.

Page Printing Concept

The 4247 processes print jobs in terms of pages, as well as in lines and columns. A page is a logical entity whose boundaries are defined by the width and the page length. These boundaries are established during printer initialization using the printer defaults, and can be changed using the Configuration menu or by issuing the appropriate data stream controls.

As a job prints, the printer controller maintains both the logical position and the physical position on the page. If a print job does not end with a proper job terminator (for example, Form Feed), then:

v All data for the current page may not print v The next print job may be misaligned on the form v Residual data from a previous job could print with the new job.

Page Presentation

Many Epson ESC/P commands (tabs, margins, line spacing, for example) are described in terms of the presentation surface. A presentation surface is a two-dimensional surface upon which the printer positions symbols according to controls embedded in the incoming data stream. The presentation surface is defined in absolute terms by the width and depth parameters of the page size control commands (Set Page

Length, Set Horizontal Margins, for example). The physical print position does not move outside the range of these two parameters. The left margin (LM) and right margin (RM) are variable parameters within the presentation surface. The logical print position does not move outside the range of the vertical margins nor outside the horizontal margins + 1. The following figure shows the presentation surface and the relationships of some of these parameters.

CPP Current Print Position (LM ≤ CPP ≤ RM). CPL Current Print Line MPP Maximum Print Position (in characters at current CPI) PMPP Physical Maximum Print Position. The largest number of characters that can be placed on one line

of the surface (the largest value that MPP can assume).

LM Left Margin RM Right Margin MPL Maximum Page Length (in lines at current LPI)

Notes:

1. The host should set the limits of the presentation surface if the default or previous values are not acceptable.

2. The operator should align the physical paper so that it matches the logical presentation surface.

Also created with this surface is a pair of numbers (CPL and CPP) which specify the line number and column number where the next graphic will be printed. These internal values are the logical position on the presentation surface.

The variable parameters have default values which are established when the printer is initialized. The standard power-on defaults are:

MPP (width) Operator panel setting

40 Programmer Manual

MPP (depth) Operator panel setting CPI Operator panel setting LPI Operator panel setting LM 0 inches (Column 1) RM Equal to MPP HT Horizontal tabs are set at each 8th column, starting with column 9 (9, 17,

VT Vertical tabs are all cleared

One-Byte Controls

Note: Control hex values within parentheses are recognized only within PC Character Set 1.

The printer uses the following one-byte controls:

Control Hex Name

NUL 00 (80) Null (no operation) BEL 07 (87) Bell BS 08 (88) Backspace HT 09 (89) Horizontal Tab LF 0A (8A) Line Feed VT 0B (8B) Vertical Tab FF 0C (8C) Form Feed CR 0D (8D) Carriage Return SO 0E (8E) Shift Out (Double-Wide Print) SI 0F (8F) Shift In (Condensed Print) DC1 11 (91) Device Control 1 (Parallel Select) DC2 12 (92) Device Control 2 (Cancel Condensed Print) DC3 13 (93) Device Control 3 (Parallel Deselect) DC4 14 (94) Device Control 4 (Cancel Double-Wide Print) CAN 18 (98) Cancel SP 20 Space DEL 7F Delete Character

Null (NUL)

00

This control terminates the Set Horizontal Tab and Set Vertical Tab control codes. The printer ignores NUL by itself.

Bell (BEL)

07

This control causes the audible alarm to sound.

Chapter 2. Epson FX-1050 Data Stream 41

Backspace (BS)

08

This control moves the print position horizontally one character width to the left. If the current print position is at the left margin, the printer ignores this command.

Horizontal Tab (HT)

09

This control moves the print position to the next horizontal tab stop. If there are no tab stops to the right, or if the next tab stop is beyond the current right margin, the control is ignored.

Line Feed (LF)

0A

This control advances the paper one line. The horizontal position does not change unless automatic carriage return mode is activated from the operator panel Configuration menu. If the paper advance crosses the bottom margin, the printer completes all deferred printing on the current page and then does an automatic form feed.

If skip perforation mode is active and the bottom margin is crossed, the vertical position on the new page following the automatic form feed will be the top-of-form position. If skip perforation is not active, the vertical position on the new page is the point immediately following the previous print line.

Vertical Tab (VT)

0B

This control causes the vertical presentation position to be advanced to the next vertical tab stop. The horizontal position is not affected unless automatic carriage return mode is activated from the operator panel Configuration menu. If there are no tab stops past the current vertical presentation position, Vertical Tab is treated as a Line Feed.

Form Feed (FF)

0C

This control causes a new page to be started. Form Feed is a line end and page end control; it causes all deferred printing that may have been buffered for the current page to be completed and the form physically advanced to eject the current page. The vertical presentation position advances to the top margin and the horizontal presentation position is set to the left margin for subsequent printing.

Carriage Return (CR)

0D

42 Programmer Manual

This control moves the current horizontal print position to the left margin. If Carriage Return equals Carriage Return + Line Feed, a Line Feed is executed when Carriage Return is received. Otherwise, the vertical position does not change. Carriage Return is a line ending control code that causes buffered data to print.

Shift Out (SO) / Double-Wide Print

0E

This control causes the printer to start double-width printing. Double-width printing prints the characters twice as wide as the current character spacing. This results in half as many characters per inch. Each character takes up the space of two single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab, Double-Wide Continuous Mode, Cancel Double-Wide Print, or Set Presentation Position with vertical movement specified cancels the Shift Out control code.

Shift In (SI) / Condensed Print

0F

This control prints graphic characters in condensed pitch (15, 17.1, or 20 CPI). If the current print option is 10 CPI this control will condense printing to 17.1 CPI. If the current print option is 12 CPI this control will condense printing to 20 CPI. If the current print option is 15 CPI there is no change in density. This control changes the maximum number of characters that can be printed on one line. Shift In is a buffer terminating control; if printable data at a different character-per-inch setting is buffered, that data is printed before the setting is changed. The current presentation position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 1 (DC1) / Select

11

This control selects the printer.

Device Control 2 (DC2) / Cancel Condensed Print

12

This control cancels or ends condensed (17.1 or 20 CPI) printing. DC2 is a buffer terminating control; if printable data at a different characters-per-inch setting is buffered, that data is printed before the setting is changed. The current presentation position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 3 (DC3) / Deselect

13

This control is treated as a NUL.

Chapter 2. Epson FX-1050 Data Stream 43

Device Control 4 (DC4) / Cancel Double-Wide Print

14

This control cancels double-wide printing if double wide was selected with the Shift Out control. The characters-per-inch setting returns to the previous value.

Cancel (CAN)

18

This control purges all buffered data. All data received after the most recent buffer terminating control is discarded. For a list of buffer terminating controls, see “Buffer Terminating Conditions” on page 72. Any data received after Cancel is processed normally. Cancel does not change the current presentation position.

Space (SP)

20

This control moves the print position one character space to the right.

Delete Character (DEL)

7F

This control removes the last text character on the print line and does not affect control codes.

Escape Sequence Controls

Escape sequence controls have an ESC followed by one or more control parameters. Supported escape sequence controls are:

Escape (ESC)

1B

This control is a prefix used in combination with supplementary control bytes to provide an extended set of control functions.

Null (ESC NUL)

1B 00

The printer ignores the NUL control by itself.

Bell (ESC BEL)

1B 07

46 Programmer Manual

This control causes the audible alarm to sound, if enabled. The alarm may be disabled or enabled from the Configuration menu.

Backspace (ESC BS)

1B 08

This control moves the print position horizontally one character width to the left. If the current print position is at the left margin, the printer ignores this command.

Horizontal Tab (ESC HT)

1B 09

This control moves the print position to the next horizontal tab stop. If there are no tab stops to the right, or if the next tab stop is beyond the current right margin, the control is ignored.

Line Feed (ESC LF)

1B 0A

This control advances the paper one line. The horizontal position does not change unless automatic carriage return mode is activated from the operator panel Configuration menu. If the paper advance crosses the bottom margin, the printer completes all deferred printing on the current page and then does an automatic form feed.

If skip perforation mode is active and the bottom margin is crossed, the vertical position on the new page following the automatic form feed will be the top-of-form position. If skip perforation is not active, the vertical position on the new page is the point immediately following the previous print line.

Vertical Tab (ESC VT)

1B 0B

This control causes the vertical presentation position to be advanced to the next vertical tab stop. The horizontal position is not affected unless automatic carriage return mode is activated from the operator panel Configuration menu. If there are no tab stops past the current vertical presentation position, Vertical Tab is treated as a Line Feed.

Form Feed (ESC FF)

1B 0C

This control causes a new page to be started. Form Feed is a line end and page end control; it causes all deferred printing that may have been buffered for the current page to be completed and the form physically advanced to eject the current page. The vertical presentation position advances to the top margin and the horizontal presentation position is set to the left margin for subsequent printing.

Chapter 2. Epson FX-1050 Data Stream 47

Carriage Return (ESC CR)

1B 0D

This control moves the current horizontal print position to the left margin. The vertical print position does not change unless automatic line feed mode is active.

Shift Out (ESC SO) / Double-Wide Print

1B 0E

This control causes the printer to start double-width printing. Double-width printing prints the characters twice as wide as the current character spacing. This results in half as many characters per inch. Each character takes up the space of two single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab, Double-Wide Continuous Mode, Cancel Double-Wide Print, or Set Presentation Position with vertical movement specified cancels the Shift Out control code.

Shift In (ESC SI) / Condensed Print

1B 0F

This control prints graphic characters in condensed pitch (15, 17.1, or 20 CPI). If the current print option is 10 CPI this control will condense printing to 17.1 CPI. If the current print option is 12 CPI this control will condense printing to 20 CPI. If the current print option is 15 CPI there is no change in density. This control changes the maximum number of characters that can be printed on one line. Shift In is a buffer terminating control; if printable data at a different character-per-inch setting is buffered, that data is printed before the setting is changed. The current presentation position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 1 (ESC DC1) / Select

1B 11

This control selects the printer.

Device Control 2 (ESC DC2) / Cancel Condensed Print

1B 12

This control cancels or ends condensed (17.1 or 20 CPI) printing. DC2 is a buffer terminating control; if printable data at a different characters-per-inch setting is buffered, that data is printed before the setting is changed. The current presentation position becomes the next printable column at the new character-per-inch setting. CPI can be changed within a print line.

Device Control 3 (ESC DC3) / Deselect

1B 13

This control is treated as a NUL.

48 Programmer Manual

Device Control 4 (ESC DC4) / Cancel Double-Wide Print

1B 14

This control cancels double-wide printing if double wide was selected with the Shift Out control. The characters-per-inch setting returns to the previous value.

Cancel (ESC CAN)

1B 18

This control purges all buffered data. All data received after the most recent buffer terminating control is discarded. For a list of buffer terminating controls, see “Buffer Terminating Conditions” on page 72. Any data received after Cancel is processed normally. Cancel does not change the current presentation position.

Set Intercharacter Spacing (ESC SP)

1B 20 NN

This control sets the amount of space to be added to the right of each character. The number of units of space is equal to NN, from 0 to 127. Each unit of space is 1/120th of an inch.

Master Select (ESC !)

1B 21 NN

This control selects any valid combination of the modes in the table below. To determine the value of the NN, add together the values of the modes you select from the table.

Mode Decimal Hex

10 CPI 0 00 12 CPI 1 01 Proportional 2 02 Condensed 4 04 Emphasized 8 08 Double-Strike 16 10 Double-Wide 32 20 Italic 64 40 Underline 128 80

This control applies to DP and NLQ. Proportional cannot be condensed and 10 CPI cannot be combined with 12 CPI. Proportional overrides condensed if both proportional and condensed are selected. Double-strike is ignored in NLQ.

Cancel MSB Control (ESC #)

1B 23

Chapter 2. Epson FX-1050 Data Stream 49

Cancels the most significant bit (MSB) control.

Set Absolute Print Position (ESC $)

1B 24 N1 N2

This control specifies the distance that subsequent characters are to be printed from the set left margin in 1/60 inch units. Where the total number of dots equals N1 + (N2 × 256). If the position is beyond the right margin, the control is ignored and the previous setting remains active. If the position is within the right margin, subsequent characters will be printed at (N1 + [N2 × 256])/60 inches.

Select User-Defined Set (ESC %)

1B 25 NN 00

This control specifies the character set as default or user-defined. The following are the values of NN: 0 Selects the default character set. 1 Selects the user-defined character set.

Define User-Defined Characters (ESC &)

1B 26 NN MM W0 W1 W2 D0...DN

This control allows the definition of special characters that are not present in the character sets.

NN and MM are two decimal numbers that define the first and last characters to be replaced in the character set in use. If you want to replace only one character, MM must be equal to NN. Any value in the range of 0 to 127 is accepted, even code 32, which is the space character.

W0, W1, and W2 are numbers that specify the width of the character and the space around it. The space on the left of the character (in columns of dots) is specified by W0; the space on the right of the character is specified by W2. W1 specifies the number of columns of dots that must be printed to design the character.

The following table lists the maximum value for W0, W1, and W2:

Printing W0 + W1 W0 + W1 + W2

DP 9 12 NLQ at 10 CPI 35 36 NLQ at 12 CPI 29 30 Proportional 41 42

D0...DN is the data of the character that is printed. Three bytes are needed for each column because it is composed of 24 dot positions. In this way, the number of data bytes is W1 x 3. You can define a character in superscript or subscript. Two bytes are needed for each column because it is composed of 16 dot positions. The number of data bytes is W1 x 2.

This control sets the line spacing to eight lines per inch.

Chapter 2. Epson FX-1050 Data Stream 51

The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 55.

Set 7/72 Inch Line Spacing (ESC 1)

1B 31

This control sets the line spacing to 7/72 inch.

The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 55.

Set 1/6 Inch Line Spacing (ESC 2)

1B 32

This control sets the line spacing at the value set by the last Set Text Line Spacing (ESC A) control received. The printer sets the line spacing to six lines per inch if no ESC A has been issued.

Set n/216 Inch Line Spacing (ESC 3)

1B 33 NN

This control changes the line spacing to the value specified by NN.

NN is a value that specifies the line spacing in units of 1/216 inch. Valid values are 0 to 255. If NN equals 0, the printer ignores this control.

The application program is responsible for keeping track of the vertical position on the current page relative to the current line spacing. Changing the line spacing within a print job without changing the page length can cause printing on the page perforation. For additional information, see “Set Page Length (ESC C)” on page 55.

Select Italic Mode (ESC 4)

NN is a one-byte hexadecimal number that specifies the line spacing value of NN/72 inches.

The value of NN is 0 to 85. Following are example values for NN: X'18' 3 LPI X'12' 4 LPI X'0C' 6 LPI X'09' 8 LPI X'08' 9 LPI X'06' 12 LPI

Set Vertical Tabs (ESC B)

1B 42 N1 N2...00

This control sets the vertical stops. The maximum number of tab stops supported is 16. The settings are not affected by subsequent changes in line spacing. The tab settings must be in ascending order (N1, N2, etc.) with the 0 character indicating the end of the command. Values of N are 1 to 255. All settings are stored in Channel 0. See “Select Vertical Tabs in Channels (ESC b)” on page 60. To clear the tab settings, use ESC B 0.

54 Programmer Manual

Set Page Length (ESC C)

1B 43 LL IN

This control sets the physical page length in lines or inches and resets skip perforation mode.

LL is a one-byte hexadecimal number that specifies the page length in lines. The value is converted to inches based upon the current line spacing. Valid values for LL are X'01' to X'FF', but the resulting page length in inches must be less than 113.8 inches (2890 mm). If LL equals 0, then parameter II (length is inches) is used.

IN is a one-byte hexadecimal number that specifies the page length in inches. IN is present only if parameter LL equals 0. Valid values for IN are X'01' to X'71'. If IN is greater than the maximum value, the maximum value is used. If both LL and IN are zero, the control is ignored.

Set Horizontal Tabs (ESC D)

1B 44 TT...TT 00

This control sets the horizontal tab stops. The maximum number of tab stops supported is 32. The sequence terminates with the NUL control code. If the null terminator is missing, the printer treats the next 32 bytes as tab stops and ignores all the data bytes following the 32 bytes until a Null is received. If the printer receives this control code with no tabs, all horizontal tab stops are cleared.

TT is the list of tab stops as character positions relative to the left edge of the physical page. Valid values are X'01' to X'FF'. Tab stops must be specified in ascending order. Entries not in ascending order are ignored.

Begin Emphasized Print (ESC E)

End Emphasized Print (ESC F)

1B 46

This control ends emphasized print mode (bold style).

Begin Double-Strike Print (ESC G)

1B 47

This control starts double-strike printing (all text characters are double struck). Double-strike printing continues until the printer receives an End Double-Strike Print control (ESC H) or the printer is initialized.

Chapter 2. Epson FX-1050 Data Stream 55

End Double-Strike Print (ESC H)

1B 48

This control ends double-strike printing.

Printable Code Area Expansion (ESC I)

1B 49

This control defines whether codes X'00' through X'1F' and codes X'80' through X'9F' are printable characters or control characters of the active character set.

When NN equals X'01', the codes become printable characters, which allows them to be used as user-defined characters.

When NN equals X'00', the codes are returned to nonprintable characters.

Perform n/216 Inch Line Feed (ESC J)

1B 4A NN

This control performs a vertical move relative to the current presentation position.

NN is a one-byte hexadecimal value that specifies the move amount in units of 1/216 inch. The printer will adjust the value to the nearest 1/144 inch. This control performs an immediate line feed, but does not affect subsequent line spacing and does not produce a CR.

Select Single Density Graphics Mode (ESC K)

1B 4B LL HH NN...NN

This control prints the supplied bit image data at 60 horizontal pel by 72 vertical pel. Bit image data can be mixed with text data on the same line.

A two-byte count (LL HH) indicates the number of bytes that follow in this control. LL is the least significant byte of the count; HH is the most significant byte. (The number of bytes that follow should equal HH × 256 + LL.) If the count equals X'0000', the control is ignored.

NN...NN are the bytes containing the bit image data. The data format is in 8-bit vertical slices, with the least significant bit the bottom dot and the most significant bit the top dot. B'1' indicates a pel to be printed; B'0' indicates an unprinted pel. Data that exceeds the right margin is discarded.

Select Double Density Graphics Mode (ESC L)

1B 4C LL HH NN...NN

This control prints the supplied bit image data at 120 horizontal by 72 vertical pel. Bit image data can be mixed with text data on the same line.

Chapter 3. Intelligent Printer Data Stream

This chapter explains the concepts of the Intelligent Printer Data Stream (IPDS). IPDS is an orderable feature for your printer. The intent of this chapter is to provide a basic overview of how IPDS works. The Intelligent Printer Data Stream Reference provides detailed information about IPDS programming in general while Chapter 4, “IPDS Programming Information,” on page 99 provides a detailed description of the IPDS commands that the 4247 Model X03/Z03 printer uses. If the programming information in the Intelligent Printer Data Stream Reference is different from the programming information in this manual, use this manual to program the 4247 Model X03/Z03 printer.

Overview

The Intelligent Printer Data Stream (IPDS) is a structured-field data stream for managing and controlling printer processes. IPDS uses all points addressability that allows users to position text, images, graphic pictures, bar codes, and overlays at any defined point on a printed page. Later pages in this chapter explain each of these data types and their uses.

IPDS offers the flexibility of creating data and commands independent of the type of attachment protocol used by the printer or its system. Using the same data stream, printers can attach to control units or any type of network link that does not restrict the transmission of data to the printer.

IPDS commands within the data stream enable the host processor to control and manage the downloading of symbol sets and stored objects, such as overlays and page segments. The printer can later use these stored objects to construct a printed page.

The IPDS command structure also provides the means for returning error information to the host, for returning query information, and for performing error recovery actions.

Physical Medium

The 4247 Printer defines the physical medium as an area with boundaries of width and depth that define the limits of this page. The maximum print position (MPP) defines the width of the current page in characters.

MPP x 1/CPI = width in inches (CPI is the number of characters per inch).

The maximum page length (MPL) defines the depth of the current page in lines.

MPL x 1/LPI = depth in inches (LPI is the number of lines per inch).

The top margin on this page is the top-of-form position, as selected by pressing SET TOP OF FORM on the operator panel. Figure 5-1 shows the physical medium layout.

75

Figure 1. The Physical Medium

The physical medium defined above is assumed to coincide with the actual physical medium (form) as that terminology is used in the following discussion.

IPDS Coordinate Systems

IPDS uses coordinate systems to define any point on a page. All IPDS commands containing location parameters use these coordinate systems to define distance measurements. The coordinate systems specify these distances in logical units called units.

Many IPDS commands contain parameters that specify values for position or size in units. For example, one unit may equal approximately 0.018 mm (0.0007 in. [1/144 in.]). Before using these values, the 4247 Printer truncates the specified values to multiples of 0.18 mm (0.007 in. [1/1440 in.]) for all unit parameters except those associated with DP, and DP Text baseline positioning. The 4247 Printer truncates DP, and DP Text baseline positioning parameters to multiples of 0.36 mm (0.014 in. [1/72 in.]). The unit parameters are identified in Chapter 4, “IPDS Programming Information,” on page 99.

X and Y Medium Coordinate System

The Xmand Ymcoordinates, known as the medium coordinate system, relate directly to the physical medium. The X change the origin and the orientation of these coordinates. The origin (X left hand corner of the physical medium. Positive Xmvalues begin at the origin and increase along the top of the sheet, from left to right. Positive Y sheet moving downward toward the bottom of the sheet. Figure 2 on page 77 shows the Xm,Ymcoordinate system:

Figure 2. The Xm,YmMedium Coordinate System

Logical Page Layout

IPDS describes the printed output in terms of logical pages. The logical page does not have to be contained completely on the physical medium. However, printing can only occur where the two areas overlap. Figure 3 shows the physical-logical page relationship.

Figure 3. The Physical-Logical Page Relationship

The logical page reference corner is the corner of the logical page that is at the smallest Xp, Yp position. This corner does not necessarily have to coincide with the physical medium origin (X

=0, Ym=0). The

m

logical page size in the X dimension is the 'X-Extent', and the logical page size in the Y dimension is the 'Y-Extent'. IPDS commands specify the logical page size and location. Figure 5-4 shows the relationship

Chapter 3. Intelligent Printer Data Stream 77

between the X and Y coordinates and the logical and physical medium.

Figure 4. The X and Y Coordinate System and the Logical Page

I and B Coordinate System

In addition to the X,Y coordinate system, IPDS uses another coordinate system, the I-B coordinate system. These coordinates describe the placement and orientation of text or images on the logical page. The printer places characters along the I-axis for a line of text. The B-axis is the direction in which the printer places lines of text on the logical page. IPDS commands can change both the origin and the orientation of the I and B axes (see Figure 5 on page 79).

Direction: As the printer places text characters on the page, the inline coordinate increases. The direction of this increase is the positive inline direction or +I. The baseline coordinate also increases as the printer places text lines on the page. The direction of this increase is the positive baseline direction or +B. Location parameters within the IPDS commands specify the I and B directions. Chapter 4, “IPDS Programming Information,” on page 99 contains specific information about these commands.

Distance: The inline coordinate increases a predetermined distance as the printer places the text characters on the page. This distance is the character increment. The baseline coordinate also increases a predetermined distance as the printer places lines of text on the page. This distance is the baseline increment. Location parameters within the IPDS commands specify the I and B distances. Chapter 4, “IPDS Programming Information,” on page 99 contains specific information about these commands.

Initial coordinates: The coordinates of the first print position on the logical page are the initial coordinates. The initial inline print coordinate is I

. The initial baseline print coordinate is Bi.

i

Current coordinates: The coordinates of the current print position on the logical page are the current coordinates. The current inline print coordinate is I

. The current baseline print coordinate is Bc. Figure 5

c

on page 79 shows the various I and B coordinates on the logical page:

78 Programmer Manual

Figure 5. The I and B Coordinate System on the Logical Page

Notes:

1. The 4247 Printer text character box is 180 units high by 144 units wide at 10 CPI when the X

pYp

units equal 1,440 per inch. The left edge of the character box is at the specified inline position and the bottom edge of the character box is 20 units below the specified baseline position.

2. If the bottom edge of the character box falls below the printable area on the physical medium, the character will not print. In this situation, a baseline move (Relative Move Baseline or Absolute Move Baseline) text command can place the character box totally within the printable area.

Processing IPDS Commands

The structured field format of IPDS allows one or more commands to be sent to the printer in a continuous stream. Each command is self-describing; the command length, type, optional parameters, and data are all part of each specific command. The printer processes each command in the order it is received. Every IPDS command contains a flag byte. Setting the Acknowledgment Required bit on in this flag byte indicates to the printer the end of a command stream sequence. The printer then sends an Acknowledge Reply to the host. Figure 6 shows an example of an IPDS data stream:

Figure 6. An Example of the IPDS Data Stream

Chapter 3. Intelligent Printer Data Stream 79

IPDS Command Format

All of the printer commands use the following format:

Length Command Flag Correlation ID Data

Note: Bit numbering follows the EBCDIC convention with bit zero being the most significant bit. A

description of each field follows.

Length

Length is a two-byte field that specifies the length of this command. This count includes the two-byte length field, the command field, the flag byte, and the optional fields (Correlation ID and Data Fields). The Length field can be any value from 5 to 32,767 (X'7FFF').

Command

Command is a two-byte field that specifies the IPDS command code. See Table 1 on page 81 for a list of valid command codes.

Flag

Flag is a one-byte field that contains the IPDS command stream flags.

Bit 0 of this byte is the Acknowledgment Required (ARQ) flag. If this bit is on, the host requests the printer to send an Acknowledge Reply.

Bit 1 of this byte is the Correlation ID flag. If this bit is B'1', a two-byte correlation number follows this flag byte. If this bit is B'0', the optional correlation number is not present and the following byte or bytes contain the data field.

Bit 2 of this byte is the acknowledgement continuation flag. If this bit is B'1', the host is requesting continuation of the current Acknowledge Reply. If this bit is B'0', the host is not requesting continuation.

Bits 3-7 of the flag byte are reserved and must be zero.

Correlation ID

Correlation ID is a two-byte value that specifies an identifier for this command. The Correlation ID is an optional field and is only present if bit 1 of the flag byte is B'1'. The printer can use any value between 0000 and FFFF for this ID. If an error occurs on a command prior to acceptance for processing, the printer sends a negative acknowledgement (NACK) to the host. If the printer recognizes the command that caused the error, the Correlation ID field in the NACK will contain the ID of the command responsible for the NACK. Correlation ID is also returned in response to commands that request information and commands that request an acknowledgement.
