Introduction

The TallyGenicom 7265 provides rugged, versatile impact printers useful in a variety of

applications. Flexibility of use is guaranteed by the wide range of software emulations and programming options. The current printer characteristics are the result of years of application experience. It is a hallmark of TallyGenicom products that they may be used with a broad

range of systems, hardware, emulations, and protocols.

7265 Programmer’s Manual

ANSI

The TallyGenicom im ple m entation of ANSI X3.64 is the native control protocol for the 7265

printer, as it is for a variety of other TallyGenicom impact matrix printer families. The control functions presented here are a superset of ANSI control sets familiar to our customers. For the most part, ANSI drivers written for other TallyGenicom printers should only need to be modified as features introduced on the 7265 Series printers are exercised. Examples of such new features include user-defined formats, alternate paper paths, user-defined character substitutions, and remote selection of emulations.

Enabling the application to select among emulations provides access to some of the 7265 features not supported in emulated products. Toward this end, the printer can be commanded to maintain the current status of fonts, pitches, tabs, margins and so forth across emulation changes. Although some minute differences due to translations from, say, columns to decipoints may be discernible when switching from one emulation to another, the printer is quite predictable when switching from another emulation to ANSI and then back again.

The 7265 is a decipoint machine. Locations and dimensions such as tabs, margins, absolute and relative positions, and form lengths are described in ANSI control sequences in units of 1/720 inch. If you have the choice of describing your page in one or another of the supported emulations, consider that ANSI gives you more flexible control of locations of objects on the page.

In this chapter we include spaces between characters in escape sequences for clarity. ESC H, for instance, is easier to read than is ESCH. Where the space character forms a component of a control sequence, then it is designated by <SP> .

Listed below are the control codes interpreted by this printer, along with page numbers where you can find detailed descriptions.

8-bit Control Codes

ANSI assigns control functions to characters 80 hex through 9F hex and calls these characters C1 codes. You can set the printer to either interpret 80 hex - 9F hex as control codes or not. The ISU default status of this option is disabled.

You can toggle the status of the 8-bit control code enable from the Emulations Options Menu or with escape sequences. The pertinent escape sequences are the ANSI private use sequences described on page 12. In 8-bit mode, all of the lower contro l codes and ESC sequences remain active. For example, you can use either PLD or ESC K for subscript printing. In 7-bit mode, only ESC K is available.

If 8-bit control code interpretation is disabled, then the printer processes characters 80 hex through 9F hex according to IBM PC character sets 1 or 2, depending on which is currently selected. The default is character set 1. You can toggle the character set selection from the Emulation Options Menu.

If 8-bit control code interpretation is disabled and character set 1 is active, then the printer strips the most significant bit of characters 80 hex through 9F hex. For example, if you send 8A hex when 8-bit control code interpretation is disabled and character set 1 is active, then the printer treats 8A hex as 0A hex and performs a line feed.

Pr inter Handshaking

Commands Description

DC1 PRINTER READY

In serial interface, if the printer is strapped for XON/XOFF handshaking, then the printer sends DC1 to the host to signal that the printer is ready to accept data.

In parallel interface, if the printer is strapped for select/ deselect by received DC1/DC3 codes, then the host sends DC1 to the printer to set the printer online.

Dec 17 Hex 11

DC3 PRINTER NOT READY

In serial interface, if the printer is strapped for XON/XOFF handshaking, then the printer sends DC3 to the host to signal that the printer cannot, for the moment, accept any more data.

In parallel interface, if the printer is strapped for select/ deselect by received DC1/DC3 codes, then the host sends DC3 to the printer to set the printer to Standby. In Standby, the printer will accept and acknowledge data from the interface, but will discard all data received.

Dec 19 Hex 13

ETX ETX/ACK COMMUNICATION PROTOCOL

In serial interface, if the printer is strapped for ETX/ACK handshaking, then the host sends the ETX control code at the end of a block of data.

Dec 3 Hex 03

Printer Control

Commands Description

SO SHIFT OUT

You can strap the printer to start either barcode (page 37) or oversized (page 64)

mode, whichever is enabled, on receipt of SO. The ISU status of SO/SI control is disabled. You can enable SO/SI control from Software Options on the printed menu,

or from the host via the Straps and Options control sequence. See page 14.

Dec 14 Hex 0E

SI SHIFT IN

If the printer is strapped to turn on barcode or oversized on receipt of SO, then SI

turns barcode (page 37) or oversized (page 64) mode off.

Dec 15 Hex 0F

ESC ESCAPE

Introduces an escape sequence. The printer evaluates characters following the ESC character to determine if the sequence is valid. If the sequence is valid, then the printer responds to the command. If the sequence is not valid, then the printer aborts the process, discarding at least the first character following ESC.

you send a command to change paper paths and there is more paper downstream of the print head than 1/2 times the current form length or six inches, whichever is greater, then the printer returns paper to the position that was current before the command was received, and a fault condition is set.

If you send a command to change paper paths and the target path is the current path, then the printer executes a form feed. If you load tractor 2

when tractor 2 is not installed, the command will be ignored.

expanded printing is selected, the current font is expanded horizontally and vertically in 100% increments according to expansion factors specified by ESC

[(p1);(p2)<SP>B (see page 11). The range of expansion is 1x through 8x.

Example: select expanded printing Dec 27 91 50 116 Hex 1B 5B 32 74

ESC [(p1); (p2)<SP>B

GRAPHIC SIZE MODIFICATION Sets the size of expanded and oversized characters. The effect of this command on

oversized is explained in a separate chapter. When expanded print is selected, the argument units for parameters p1 and p2 are

percentages of the vertical and horizontal dimensions of the current font. Parameter p1 controls the vertical expansion and p2 controls the horizontal expansion. The argument limits for expanded print are 800;800 (8x the parent font size).

Oversized enables much larger expansions. Parameters are rounded down to the nearest 100.

Note: This printer goes into expanded mode immediately on receiving this command. Any text between this sequence and a countermanding ESC [(p1)t

sequence (see page 11) is printed according to the specified expansion.

If height and width are different values, the height will be set the same as the width.

PAPER SHEAR If the paper shear option is installed, then note that the appropriate strap must be set

in the hardware options menu in order for the paper shear to work. Parameter p1 = 1 selects the paper shear. Parameter p2 = 1 executes a cutting sequence: If the vertical position is not at top-of-

form, then a form feed is executed. Paper is advanced to the shear position and cut. Next, it is advanced an inch to eject the sheet that has been cut off; then it is retracted to the top margin on the following form. The horizontal position following a shear is the left margin. The shear position should be set from the control panel so that paper is cut precisely at the perforation. If a non-zero top print reference is needed, then set the top print reference first and then set the shear position.

Line/Character Spacing

Command Description

ESC [(p1); (p2) <SP> G

LINE/CHARACTER SPACING Sets the vertical and horizontal pitch in decipoints. Parameter (p1) is the

spacing between lines and (p2) is the spacing between characters. Unspecified parameters remain at their current values. This command does not affect oversized printing selected by ESC [1t.

Commands Description

ESC [(p1); (p2) <SP> G

LINE/CHARACTER SPACING p1 = line spacing parameter p2 = character spacing parameter If you select doublewide printing (ESC [5m), then the printer doubles character

spacing set by this command. If the designed pitch of the current font is 10 cpi and doublewide is set, then a character spacing argument of 72 results in a pitch of 5 cpi, at which horizontal segments of line-draw characters are contiguous.

Example: ESC [90;60 <sp> G sets the vertical spacing to 8 lines per inch and the horizontal spacing to 12

characters per inch. (720 divided by 8 = 90, and 720 divided by 12 = 60).

Forms Setup

Command Description

ESC [(p1); (p2);(p3);(p4) ;(p5)r

FORMS SETUP Sets top of form and sets form length, as well as top and bottom margins, in decipoints.

Parameter p1 is form length 720ths , p2 is the top margin, p3 sets the length of white space between the baseline of the last allowed

line and the end of form. p4 is the top print reference, and p5 is the left print reference Any parameter not specified is assigned its default value. Maximum form length is

15840 decipoints (22 inches).

Default Values

p1 7920 decipoints 11-inch form p2 0 decipoints 0-inch top margin p3 0 decipoints 0-inch bottom margin p4 0 decipoints 0-inch top print reference p5 0 decipoints 0-inch left print reference Example: Set 8-inch form length, one-inch top margin, one-inch bottom margin

target paper path. One way to do this is to park and then load paper in the target path. The top edge of the paper should line up with the top of the print head. If not, then set the top print reference to zero from the menu and save the change to the format associated with the target paper path. You must once again park and load paper in the target path in order for the new print reference to take effect.

Next, send a command to set the vertical position-absolute to zero. If you do not do this, then the printer establishes top-of-form at the current top margin, and form registration is lost.

Superscript/Subscript

Command Description

ESC K (PLD)

ESC L (PLU)

NOTE: The partial line up does not respect top of form; that is, following a form feed, ESC L causes a partial line movement upward. Also, partial line down does not respect bottom of form; that is, when printing the last line on the form, ESC L causes a partial line movement downward.

SUBSCRIPT PRINTING Moves paper 1/2 line below the current line for subscript printing. ESC K is used to

return to the original line following ESC L (superscript). If 8-bit control code processing is enabled then Dec 139 Hex 8B otherwise Dec 27 75 Hex 1B 4B SUPERSCRIPT PRINTING Moves paper 1/2 line above the current line for superscript printing. ESC L is used to

return to the original line following ESC K (subscript). If 8-bit control code processing is enabled then Dec 140 Hex 8C otherwise Dec 27 76 Hex 1B 4C

When printing the last line on a form, do not send a line feed (LF) code to move directly from superscript to subscript. The LF code will be acted upon as the bottom of form terminator.

Vertical Movement

Absolute positions are calculated from the top and left print references without respect to margin settings. The top of a character cell located at vertical position-absolute 0 is at top print reference. The left edge of a character cell located at horizontal position-absolute 0 is at the left print reference. If the default left print reference is current, and if the left tractor position(s) are as shipped, then this is about 0.6 inches from the left edge of the paper.

Top and left print references are adjustable from the printer menu.

Dec 141 Hex 8D

Commands Description

ESC [(p)e VERTICAL POSITION RELATIVE

Advances paper p decipoints. This command enables printing below the bottom

margin of the current form and above the top margin of the following form. The

example below advances the paper 4 1/4 inches.

Example: ESC [3060e

Dec 27 91 51 48 54 48 101 Hex 1B 5B 33 30 36 30 65 ESC [(p)k VERTICAL POSITION BACKWARDS

Moves the vertical position backwards to (p) decipoints above the current position.

The horizontal position does not change.

If the target position is above the top margin, then the vertical position is the top

margin. If no top margin is set, and the target position is above top-of-form, then the

vertical position is top-of-form.

NOTE: The printer economizes vertical motion with vertical logic seeking, so this

command may cause reverse paper motion in some instances and not in others.

Reverse paper motion can cause problems with some forms.

Example: ESC [1080k moves the vertical position up by 1.5 inches.

Dec 27 91 49 48 56 48 107 Hex 1B 5B 31 30 38 30 6B ESC [(p)d VERTICAL POSITION ABSOLUTE

Moves the current print position to p decipoints from the top of the form.

The following example advances the paper to 2 inches below top of form.

Example: ESC [1440d

(p2)f

VERTICAL AND HORIZONTAL POSITION ABSOLUTE

Moves the print position to any coordinate on the page. Coordinates are measured

in decipoints. Parameter p1 is the vertical coordinate, which is measured from the

top print reference. Parameter p2 is the horizontal coordinate, which is measured

from the left print reference. The computation of absolute positions is not influenced

by margin settings. Top and left print references are adjustable from the control

panel.

You can print characters beyond the left, top, and bottom margin setting, but no

printing is allowed beyond the right margin.

EXAMPLE: ESC [1440;2160f

Prints the next character 2 inches from the top print reference and 3 inches from the

left print ref erence.

Horizontal Movement

Commands Description

HT HORIZONTAL TAB

Causes the current print position to move to the next tab stop. If no tabs are set, then the current position moves one space. If tab(s) are set but no tab(s) are set between the active print position and the right margin, then following characters on the line are either discarded or printed on the next line, depending on the status of auto wrap.

Dec 9 Hex 09

CR CARRIAGE RETURN

Initiates printing and returns the current print position to the left margin. Dec 13 Hex 0D

ESC [(p)a HORIZONTAL POSITION RELATIVE

Advances the current print position by the distance specified. Parameter p is specified in decipoints.

Example: ESC [1080a advances the print position 1.5 inches. Dec 27 91 49 48 56 48 97 Hex 1B 5B 31 30 38 30 61

ESC [(p)j HORIZONTAL POSITION BACKWARDS

Moves the horizontal position (p) decipoints left of the current position. Actual distance between symbols separated by this command is the argument (p)

minus the current horizontal pitch (text or graphics). For example, if you print an uppercase E at 10 cpi, move backwards by (p), and print another uppercase E, then the distance between leading edges of the two characters is (p) - 72 decipoints. If you print graphics at 72 dpi, move backwards by p, and print another graphics column, then the distance between the two graphics columns is (p) – 10 decipoints.

This command enables printing left of the left margin. Any data located left of the left print reference is discarded.

Example: ESC [1080j moves the horizontal position back by 1.5 inches. Dec 27 91 49 48 56 48 106 Hex 1B 5B 31 30 38 30 6A

Dot Graphics

Dot graphics allows you to print individual dots at any position on the page and thus to print pictures as well as text. When you enter dot graphics, the printer defaults to a dot density of 72 dpi horizontally and vertically, and a line spacing of 12 lpi. Exiting from dot graphics returns the printer to its prior lpi setting. You can also choose a density of 144 dpih x 72 dpiv. The printer powers up in low density. The density remains as last set until it is changed, or until power is turned off.

Each byte of graphics data defines one column of dots that is six dots high. You can think of the least significant six bits in the byte as controlling the topmost six wires of the print head, with the first bit controlling the top wire and the sixth bit controlling the sixth wire down. If you wanted to fire all six wires, then you would send a byte with a decimal value of 63. Byte values of 0 through 31 decimal are interpreted as control codes, so you have to add 64 to any graphics data byte less than 32 decimal.

You would expect to be able to simply add the value 64 decimal to every graphics data byte; in other words, just set the seventh bit. This is risky because some variations within the 3000 product family interpret decimal 127, the Delete character, within a graphics sequence. The effect is to delete everything following the last line terminator. The safest course is:

byte_val < 32 then byte_ val = byte_val + 64

Graphics Control Functions

The set of control codes that are interpreted while in graphics mode are shown in the following charts. Bytes less than 32 decimal that are not interpreted as control codes are ignored. The printer processes valid escape sequences within a graphics data sequence. This is potentially useful, for instance, in the cases of the absolute and relative position commands. A valid escape sequence that is not applicable to graphics mode, such as bold printing mode, will be implemented for text on exiting graphics. If the printer receives a nonvalid escape sequence while in graphics mode, then it drops out of graphics mode.

ANSI Bar Codes

This chapter describes the characteristics and lists ANSI control sequences for 23 resident bar code styles. You have to be in ANSI emulation to print the resident bar codes. You can adjust various bar code attributes including rotation, height, print density, status of the human-readable line, and element widths. Subject to some constraints based on style and rotation, the humanreadable font is also selectable. For some styles, the printer will calculate checksum characters for you.

To print a bar code symbol, you need to:

1) Set the printer to ANSI emulation.

2) Send the escape sequence to set the user-adjustable attributes. Always do this at least once.

3) Send the control sequence to turn on bar code.

4) Send the ASCII representation of symbol data you want to encode.

5) Send the control sequence to turn off bar code.

6) Send a line terminator at some point thereafter.

In bar code parlance, a module is the narrowest nominal width of measure, while an element is a single bar or space. A character is a group of elements that represents a number, letter, or punctuation mark. A symbol is a group of characters that can stand alone in terms of being interpreted by the reader. A symbol always comprises one or more data characters framed by white spaces known as quiet zones. The symbol frame almost always includes start and stop characters. Depending on the style, some bar code symbols can also include check characters, center characters, and guard bars.

Among printers that generate bar codes internally and that also support any user-adjustment of bar code widths, some enable the specification of module width, while others, such as this one, enable the adjustment of element widths. From the programmer's point of view, adjustable module widths tend to guarantee that the ratio among element widths remains correct, while adjustable element widths afford more flexibility.

When we ship the printer, the ratios among element widths in a given bar code style are within generic specifications for that style. You can restore these default element widths by performing an initial setup (ISU) as described in the User's manual. Since this printer lets you specify element widths independently of each other, it is possible to print bar codes that are outside of generic specifications, or outside of the limits of your particular reading system, or both. You need to know the requirements of your system before you program your printer.

Bar codes printed with this printer are suitable for readers designed for low- or medium-density bar code symbols. Avoid readers with apertures smaller than 7 mils. If bar codes are to be read with an infrared reader, then you must use a special carbon ribbon.

The examples given in this section use the Code 3-of-9 format.

Before You Begin - Set the Form Length

Programmers tend not to trust form feeds and sometimes use line feeds instead to move from one form to another. If there is any advantage to that approach, it is that the vertical move will not depend on the current form length. When printing bar codes on labels, you can greatly simplify your task by setting a form length that exactly matches the length of your physical form and then using form feeds to make vertical moves between labels or rows of labels.

If you print nothing but text, then the vertical position following each line feed lies on a grid that is evenly spaced according to the line feed increment. If you print a bar code symbol, then positions established by subsequent line feeds may not be on that grid. The vertical position following a bar code symbol becomes the origin for a subsequent line feed; this new origin must be computed based on bar code height, and the status of the human-readable line.

If you do not initialize your vertical position with a form feed for each row of labels, then printed objects may creep cumulatively up or down with respect to the top of your physical form.

Setting Bar Code Parameters

The ANSI control sequence that sets bar code parameters has the format:

Command Description

ESC [p1;p2;p3;p4;p 5;p6;p7;p8;p9; p10;p11;p12;p 13}

General Rules for Assigning Parameters

 You can send the sequence to modify bar code parameters any time except when bar code

mode is active.

 If you assign a parameter value outside the permissible range, then that parameter value

reverts to the default value.

 Values for narrow bars must be less than values for wide bars. Values for narrow spaces

must be less than values for wide spaces. The ratio between wide and narrow elements should be about 3:1.

As with other ANSI escape sequences that take multiple parameters, you can use the semicolon as a place holder when you want to change a higher-numbered parameter while leaving lowernumbered parameters alone. For example, to set the horizontal print density to 60 dpi without changing any other bar code attributes, you could send:

ESC [;;;;;;;;;0;;}

Semicolons that trail the last specified parameter are optional. For example, to turn off the human-readable line without changing any other parameters, you could send:

ESC [;;0}

Or, you could send:

ESC [;;0;;;;;;;;;}

Note: The term “default” is misleading when applied to bar code parameters. This printer stores

bar code parameters in nonvolatile RAM while power is off; except for an ISU or an out-of-range argument, you might never see the effects of the factory defaults. For this reason, your application should probably initialize all 12 parameters one time before any symbols are sent. This is particularly true when other bar code applications are sharing the printer.

Height of the bar code in 1/12-inch increments. The default is ¾ inch, which corresponds to an argument of 9.

Caution: In some versions of the printer, the last non-zero value of p13 supplants all subsequent

values of p2 until you ISU that printer. (See page 41.)

7265 Programmer’s Manual 38

p3 - Human Readable Enable

An argument of 1 turns on the human-readable line, while 0 turns it off. The default is on. When the human readable line is enabled, it is printed in the font specified by parameter p12. There is

0.1" between the bottom edge of the bar code and the top of the characters in the human-

readable line.

Element Widths

The default element widths are the narrowest that we recommend for consistent readability. The argument units for horizontal bar code element widths are 1/120 inch. The print wire diameter

is 1/72 inch; a printed dot is about 1/60 inch in diameter. This is the finest line that the printer can make. The printer accepts an element width of 1 as a valid argument, but the actual width of the resulting element is 1/60 inch, the same as if you had specified a width of 2.

If the element width argument is greater than 2, then the printer rounds down odd numbers. A width argument of 5 produces the same result as a width argument of 4.

p4 - Narrow Bar Width

Argument units are 1/120 inch if the bar code is horizontal (0o or 180o rotation) or 1/144 inch if the bar code is vertical (90

p5 - Wide Bar Width

Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar code is vertical. The default is 6.

p6 - Narrow Space Width

Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar code is vertical. The default is 2.

p7 - Wide Space Width

Argument units are 1/120-inch increments if the bar code is horizontal or 1/144 inch if the bar code is vertical. The default is 6.

Wide space and wide bar are both set to the smaller of the two values. This sets the proportion of the large to small the same for spaces as it is for bars.

p10 - Horizontal Resolution

A value of 0 is 60 dots per inch, while a value of 1 is 1/120 dots per inch. The default depends on the style in force. EAN and UPC styles default to 1. All other styles default to 0.

Note: This parameter affects bar codes printed at 0 resolution, then bar codes are darker and are printed at a somewhat slower speed.

Caution: In some versions of the printer, a non-zero value of p13 supplants all subsequent values of p2 until you ISU that printer. To be on the safe side, if you do not plan to use p13, then set p13 to 0. NOTE: Bar code height is limited to 10 inches.

Delimiters

A bar code delimiter is a character or control function that tells the printer where one bar code symbol ends and an adjacent symbol begins. Different bar code styles accept different delimiters, which might be spaces, commas, asterisks, horizontal tabs, or horizontal position-relative commands. Valid delimiters for the various styles are listed in the Bar Code Style Characteristics section.

There is always a minimum one-fourth inch of white space called the quiet zone on either side of a bar code symbol, so there is always an irreducible half-inch space between adjacent symbols, no matter which delimiter is used. The space character occupies an additional tenth of an inch. Neither the comma nor the asterisk imposes any additional space between symbols. Asterisks are valid delimiters in Code 3 of 9 (style 4) only, and are normally used in pairs.

Horizontal Tab Delimiter

The HT control code (09) is a valid delimiter in all bar code styles. The leading quiet zone of a subsequent symbol begins at the first tab stop right of the trailing quiet zone of the current symbol. This is evident in the sample, where the quiet zone of the second symbol begins at the third tab stop.

Since this printer stores tabs in nonvolatile RAM while power is off, and since the control sequence that sets horizontal tabs does not clear existing tabs, you should clear all tabs before setting tabs. Note also that new tab stops do not take effect until you send a line terminator; in other words, you cannot set tabs for the current line.

The superfluous tab stops in the following example are included to show you how the function works. If you use horizontal tabs for delimiters, then set no more tab stops than you plan to use.

If you rotate a bar code 90o or 270o, then space imposed by delimiters is not rotated, but is applied horizontally, as the sample shows. The symbol dimensions that used to be horizontal are shortened to 120/144 of what they used to be; this includes the quiet zones.

Calculating Characters per Inch

We show characters per inch at the default element widths and 0o/180o rotation for each style in the following chapter. All of our numbers ignore the quiet zones; you need to allow 1/2 inch per symbol for the horizontal rotations.

Defining characters per inch for fixed-length codes is straightforward in that the start-stop and center characters always take up the same portion of length of the symbol. The styles that have center characters are all fixed-length.

For variable-length codes, net characters per inch depends on the number of data characters in the symbol. The overhead imposed by start-stop characters is the same whether a symbol represents 1 data character or 10, so the net cpi is greater for longer symbols. We show the overhead imposed by start-stop characters separately for the variable length codes.

The default element widths are the narrowest that we recommend. If you use wider element widths and maintain a 3:1 ratio of wide elements to narrow elements, then you can extrapolate characters-per-inch for wider symbols. If you depart from the 3:1 ratio, then it's simpler for you to print test symbols and derive formulae based on what you measure than it is for us to tell you how to do the computation for each style.

One way to determine the combined length of start-stop characters for a variable-length symbol is to print two symbols, one with twice as many data characters as the other. Measure the shorter symbol and call this L1; measure the longer symbol and call this L2. The combined length of the start-stop characters is:

d = (2 x L1) - L2

To summarize, when using our cpi figures to predict the length of a symbol, remember:

• Allow for two quiet zones per symbol.

• For variable-length symbols, allow the combined start-stop character length for each symbol.

• If you use a check character, then allow for the check character.

Bar Code Style Characteristics

The following pages show specific information about the various styles. A NULL character is a combination of bars and spaces unique to a particular style that is printed when a nonvalid character is encountered in received bar code symbol data. A null character in the symbol shows up as a diamond in the human-readable line if the HRL is enabled.

POSTNET (Style 50)

You cannot adjust POSTNET bar code attributes with ESC[(p1);..(p12)}. All attribute parameters except the style parameter (p1) are ignored by POSTNET, although they are processed, saved, and would apply to a subsequent bar code of another style if not overwritten. To select POSTNET, you need to send only ESC [50}. You cannot print human-readable characters with this bar code style.

There are three variations of POSTNET. They are ZIP, ZIP+4, and ABC. The printer determines which variation is being called for by the number of characters in the symbol string. Legal characters are the numerals 0 - 9 (30 hex - 39 hex) and the dash symbol (2D hex), which is ignored. Any other printable characters in the symbol string cause an error character (diamond) to be printed.

ZIP 5 digits plus 1 check digit

ZIP+4 9 digits plus 1 check digit ABC 11 digits plus 1 check digit

The check digit is the digit that makes the sum of the digits in the symbol string, including the check digit, evenly divisible by 10. For example, if you send the ZIP symbol string "12345", then the sum of those five digits is 15, so "123455" would be the complete ZIP symbol.

If you do not send a check digit, then the printer computes it and prints it. If you do send a check digit, the printer compares your check digit with its internal computation; and if the two numbers do not agree, then an error character is printed.

Calculating the Checksum for Code 3 of 9

A 3 of 9 symbol is a variable-length string which can include the digits 0 - 9, uppercase A - Z, and six additional punctuation characters. The values used to compute the checksum for a 3 of 9 symbol are the locations of individual characters in the unique 3 of 9 character table. Your program will need to refer to a 3 of 9 look-up table to acquire values for the characters you want to encode, and again to convert the computed checksum back to a valid 3 of 9 character.

The check digit is the modulus 43 sum of all the character values in a given symbol.

1. Compute the check character for the character string:

12345ABCDE/

2. Sum the values of the characters based on their locations in the 3 of 9 character table:

1 + 2 + 3 + 4 + 5 + 10 + 11 + 12 + 13 + 14 + 40 = 115

3. Compute the modulus 43 of the sum:

115/43 = 2 Remainder 29

4. The check character is the character corresponding to location 29 in the 3 of 9 character table, which is T. Send to the printer:

12345ABCDE/T

Calculating the Checksum for CODE 93

A Code 93 symbol consists of a start code, a variable number of data characters, two check digits (referred to as "C" and "K"), and a stop code.

The values used to compute the checksum for a Code 93 symbol are the locations of individual characters in the Code 93 character table. Check digit "C" is the modulo 47 sum of the character values and a weighting sequence, where the weights from right to left are in the sequence 1, 2,

3...19, 20, 1, 2, 3...19, 20....

Check digit "K" is the modulo 47 sum of the character values and a weighting sequence, where the weights from right to left, starting with the check character "C", are in the sequence

1, 2, 3...14, 15, 1, 2, 3...14,15....

The following example illustrates the calculation of the check digits for the symbol CODE 93.

Data CODEsp93"C""K" Data Values 12 24 13 14 38 9 3 C Weights 7654321 K Weights 87654321

1) For "C", sum the products of the (C WEIGHTS * DATA VALUES).

(1 * 3) + (2 * 9) + (3 * 38) + (4 * 14) + (5 * 13) + (6 * 24) + (7 * 12) = 484

2) Divide 484 by 47.

484 / 47 = 10 remainder 14.

3) Therefore, the value of "C" is 14, which corresponds to character E.

4) For "K", sum the products of the (K WEIGHTS * DATA VALUES), starting with the newly calculated "C" digit.

(1*14) + (2*3) + (3*9) + (4*38) + (5*14) + (6*13) + (7*24) + (8*12) = 611

5) Divide 611 by 47.

611 / 47 = 13 remainder 0

6) The value of "K" therefore is 0, corresponding to character 0. Send to the printer:

CODE 93E0

The Code 93 character table is the same as the Code 3 of 9 character table, except that there are four additional “control characters” at the end.

Code 93 Checksums for Full ASCII

You can send any of the 128 ASCII characters verbatim in a Code 93 symbol. You would not need to worry about Code 93 control codes if you did not need to compute checksums.

The four control characters in the Code 93 character table do not correspond to any byte values sent to the printer, but instead refer to “precedence codes” that the printer generates. If you send the printer a lowercase “a” in a Code 93 symbol, for instance, then the printer prints bars and spaces that correspond to the <CTRL> + code in front of bars and spaces that correspond to the uppercase “A”. The reader then interprets this character combination as a lowercase “a”.

So far, this process is transparent both to routines sending symbol strings to the printer and to routines receiving decoded data from the reader. When ASCII characters are represented as character combinations, however, the reader expects to see a checksum based on the values of these combinations; this is the reason that the control codes are assigned values in the Code 93character table. The following example illustrates the calculation of the check digits for the symbol Cat :

Checksum calculation for the symbol Cat

Data C <CTRL> + A <CTRL> + T "C" "K"

Data Values 12 46 10 46 29

C Weights5432 1 K Weights654 3 21

1) For "C", sum the products of the (C WEIGHTS * DATA VALUES).

(1 * 29) + (2 * 46) + (3 * 10) + (4 * 46) + (5 * 12) = 395

2) Divide 395 by 47.

395 / 47 = 8 remainder 19.

Therefore, the value of "C" is 19, which corresponds to character J.

3) For "K", sum the products of the (K WEIGHTS * DATA VALUES), starting with the newly calculated "C" digit.

(1*19) + (2*29) + (3*46) + (4*10) + (5*46) + (6* 12) = 557

4) Divide 557 by 47.

611 / 47 = 11 remainder 40

5) The value of “K” therefore is 40, corresponding to character /. Send to the printer:

ANSI Oversized Font

This chapter describes the characteristics and lists the ANSI control sequences for the rotatable oversized font, a unique sans-serif font with character shapes designed to accommodate very large expansions. This is an industrial-strength feature. Horizontal resolution is held to 120 dpi to enable oversized printing at carriage speeds of up to 50 inches per second. Combined with vertical logic seeking, this enables the 7265 to print complex mixes of character sizes and rotations at creditable throughputs.

The oversized font is monospaced only. ANSI print modes: bold, underscored, doublewide, and proportional have no effect. You can print characters 20 hex through 7F hex; characters above this range are ignored. User-defined character substitutions do not work in oversized, so you cannot use the IBM line-draw characters. The resident international character substitutions work the same as in normal text.

In contrast to the oversized function on earlier products, the 7265 interprets escape sequences and control codes within an oversized string. As of this writing, however, we recommend that you exit oversized before sending any other control functions.

To maintain compatibility with existing printers, the 7265 printer does not back paper up to print oversized characters on the current baseline. If you enter an oversized mode and immediately print one character, then the top of the character is at the vertical position that was current when you entered oversized. This is no problem if all characters on a line are the same size. To mix oversized with either normal type or with different expansions on the same baseline, however, you will need to write a routine to find the baseline. We cover this later in this chapter.

Some of the oversized control sequences are redundant. The nonrotatable controls that let you optionally toggle oversized with SHIFT OUT and SHIFT IN are retained for compatibility with older printers. You could reasonably choose to use only the escape sequences for rotatable oversized (ESC [(Ps)| ) for new applications.

SET CHARACTER SIZE Sets the expansion of oversized characters in percentage points. Pv is the vertical

expansion and Ph is the horizontal expansion. The parent font is a 10-point font. Dimensions established by this sequence are stored in nonvolatile RAM while power is off.

Caution: Any text between receipt of this command and a countermanding mode selection command, either ESC [(Ps)| or ESC[(Ps)t, will be printed in expanded mode. If you do not want this to happen, then you must follow this command immediately with a mode selection command.

The range of valid parameters (in the sense that a valid parameter does not abort the escape sequence) is 0 <= Pn < 32767. The printer rounds off dimension parameters as follows:

If Pn < 100, then Pn = 100 If 100 < Pn < 18700, then Pn is rounded down to the nearest 100. If Pn >= 18700, then Pn = 18700 Example - to set 20-point type at 1:1 aspect ratio:

Oversized Versus Expanded

There are two ANSI functions that print characters scaled according to the Graphics Size Modification parameters. Both expanded and oversized are standard features with this printer. You can get into expanded mode accidentally when you send the Graphic Size Modification sequence.

Figure 4-1 Expanded and Oversized

Expanded mode is based on the current font, is limited to 8x the parent font size, and propagates up from the baseline. Reverse paper motion occurs for vertical expansions. The horizontal resolution reflects the current font selection. If you send a line feed character while in expanded mode, then the paper advances by the current vertical expansion factor times the current linefeed increment.

Oversized is based on a unique font, is rotatable, expandable to 1870x, and propagates down from the top of the character cell. The resolution is always 120 dpih x 144 dpiv. If you send a line feed character while in oversized, then paper advances five dot rows for 0 nine dot rows for 270 obviously better.

rotation. The scaling algorithms for the oversized function are

rotation, or

Setting the Expansion

The size of the parent oversized font is 10 points (12 cpi). You can set the horizontal and vertical dimensions of oversized characters separately in increments of 100% of the parent font size. Limits are 100% to 18,700%. The larger number corresponds to an uppercase M about 18.7 inches high. The control sequence that sets the expansion is the ANSI Graphic Size Modification:

ESC [(pv);(ph)<SP>B

where (pv) is the vertical expansion, (ph) is the horizontal expansion, and <SP> is the space character (20 hex).

For 0

rotation, you can think of parameter (pv) as 10 times the point size of the oversized character. If you set a 600 x 600 expansion and print an uppercase “E” at zero rotation, then the resulting character will nearly match the 60-point Helvetica “E” on a typesetter's scale.

A sideways character shares neither the size nor the aspect ratio of a vertical character printed at the same expansion factors. Relationships between expansion and character dimensions for

rotation reflect differences in the horizontal and vertical resolutions of the printer in

270 oversized mode.

Remember to always follow the graphic size modification command immediately with either ESC [0t or the desired oversized mode selection if you do not want to drop into expanded mode.

Device Timeout with Very Large Characters

Normally, one byte of data in the printer's input buffer represents one text character, which takes milliseconds to print. If our host creates a huge character using dot graphics, then one byte of data in the buffer corresponds to one dot column. If we set oversized, however, then one byte of data can command the printer to render several hundred thousand dot columns. A big oversized character can take a while to print.

If we fill the printer's input data buffer while a big oversized character is printing, then the printer goes BUSY. The big character, as well as a buffer full of following objects, has to be printed before the printer goes READY again.

If the host now tries for some period of time to send data to the printer without seeing a READY at the interface, then the host might decide that the printer is not working, show you a device timeout message, and abort the data transfer.

This same possibility exists with large bar codes, and we discuss remedies in the ANSI Bar Code chapter.

What is a Character Cell?

A character cell is the rectangular array of locations at which dots can be printed to form one character.

All character cells for a given monospaced font at a given pitch are the same size. If you print a line of characters with no countermanding motion instructions, then no character cell will impinge horizontally on the character cell of an adjacent character. You can determine character cell width in a monospaced font by measuring the distance from the leading edge of, say, an uppercase “E” to the leading edge of an adjacent uppercase “E”.

In an impact-matrix printer font, the printed portion of a character is often centered horizontally in the character cell. There might be a fixed number of dot columns on either end of the character cell that are never printed. This is analogous to the side bearings in a typeset character.

Figure 4-2 Character Cells

In the oversized font, on the other hand, characters are left-justified in the cells. This lets you print a larger character when you are printing, say, one huge character on a sheet. The 7265 printer prints as much of an oversized character as will fit between the margins. If your character is going to be clipped at the right margin, then you might rather clip the side bearing than clip a printed portion of that character.

In the oversized font, the topmost dot in the uppercase “E”, for instance, is centered on the upper boundary of the character cell. The lowest dot on the descender of the lowercase “j” is centered on the lower boundary of the character cell.

Oversized Character Dimensions – 0

The width of an oversized character cell is 0.72 decipoints times the horizontal expansion factor. In thousandths of an inch, it is the same as the horizontal expansion factor. If you set a horizontal expansion of 1000, then characters will be 1 inch, or 720 decipoints, apart.

Figure 4-3 Vertical Characte r Dimensions

The height of an oversized character cell is 0.9 decipoints times the vertical expansion factor. In thousandths of an inch, it is 1.25 times the vertical expansion factor. If you set a vertical expansion of 1000, then the top of the uppercase “E” is 1.25 inches, or 900 decpoints, from the bottom of the lowercase “j”.

The distance from the top of an oversized character cell to the baseline is 0.7 decipoints times the vertical expansion factor. Top of the character cell means the upper boundary of the cell before it was rotated.

Oversized Character Dimensions - 270

The width of a character cell is 0.6 decipoints times the horizontal expansion factor. Width means the dimension that is left-to-right as you read the character.

The height of a character cell is 1.08 decipoints times the vertical expansion factor. Height means the dimension that is vertical as you read the character.

Figure 4-4 Sideways Character Dimensions

The distance from the top of the character cell to the baseline is 0.76 decipoints times the vertical expansion factor. Top-of-cell means the upper boundary of the character cell as you read the character.

When printing strings of sideways characters, the printer adds horizontal space between character cells. This space is equal to 0.36 decipoints times the vertical expansion factor.

Vertical Position-Relative in Oversized

Normally, the origin of a vertical position-relative move is the current position. If the last object printed on the current line was an oversized character, however, then the origin of a vertical position-relative move is the top of that character cell, where top-of-cell means the character cell boundary that is uppermost on the paper. This is true whether or not you are still in oversized when the vertical position-relative command is sent.

Implementing the Line Feed Function - 0

A good technique is to exit oversized with ESC [0t and send a vertical and horizontal position absolute command:

ESC [(Pv);(Ph)f

where (Pv) is decipoints from the top print reference and (Ph) is decipoints from the left print reference. The logic seeking of the printer minimizes redundant paper motion associated with position-absolute commands. You could also use vertical position-relative to implement line feeds.

Try a line feed increment of 1.2 decipoints times the vertical expansion factor.

If you send a line feed character while in oversized, then paper advances five dot rows for the 0 rotation.

Line Spacing and Intercharacter Spacing - 270

If you print sideways text, then the vertical move that otherwise corresponded to a line feed now sets the distance from the leading edge of one character cell to the leading edge of the next character cell (as you read the characters). A good starting value for this move is the character cell width, which is 0.6 decipoints times the horizontal expansion factor.

Strings of sideways characters propagate left-to-right across the portrait page. The printer makes “ line feeds” for you by inserting space between the trailing cell boundary of the previous character and the leading cell boundary of the next character. This space is 0.36 decipoints times the vertical expansion factor, which is generous line spacing.

If this line spacing is not satisfactory, then send sideways text one character at a time, preceded by a locating command for each character. If you use the resident line spacing for sideways lines, then you will probably use a character array to rotate text. In that case, remember to fill your array with space characters (20 hex) before you copy strings into it.

Introduction

This User’s Manual describes the sum of all EPSON Escape sequences, regardless of the specific EPSON emulation used by your printer. The only differentiation is made between 9 and 24 needle printers as well as the maximum possible paper width of 8 inches (80 column printer) or 13.6 inches (136 column printer). Please note that the print quality LQ (Letter Quality) is only available in the 24 needle printer.

Please be sure to observe the notes and steps described in the Operator’s Manual as well as the specific EPSON emulations implemented in your printer and which of the described sequences are thus not available for that specific emulation.

Select the EPSON mode as described in the Operator’s Manual. Selecting this emulation mode will automatically select the Epson character set.

Read the Operator’s Manual to see whether it is also possible to use ANSI (MTPL) sequences in addition to the special Epson sequences.

The following explanations will help you understand the sequences better:

Every sequence description begins with a header, in which the function and the short form of the sequence are listed without parameters, e.g.:

For the parameter (here n) it is necessary to differentiate between two types of syntax.

if the parameter is in pointed parentheses, the decimal value is transferred if the parameter is not in pointed parentheses, the ASCII value is transferred

Example:

Perforation Skip

Data Structure

Description

ASCII ESC "N" <n> set space before perforation (perforation skip) hex. 1B 4E <n> dec. 27 78 <n>

ASCII ESC "O" reset perforation skip hex. 1B 4F dec. 27 79

This code sequence enables the perforation skip function and sets the bottom margin

➊

(distance between the last print line of one page and the first print line of the following page) to n lines. The value specified for n must be in the range of 1 to 127 and must be smaller than the form length minus the top margin. The printer automatically advances the paper to the first printable line of the next page whenever the current print line falls within the margin area defined as n lines from the bottom of the current page (n being the value specified for the bottom margin area). The margin area before and after the perforation is n times the current line spacing. Once this margin area has been defined, it will not be affected by changing the line spacing and remains effective until the printer receives code sequence ESC O (reset perforation skip), or until form length is changed by ESC C or ESC C 0.

This code sequence deselects the perforation skip function set by ESC N <n>.The bot-

➋

tom margin is set to 0 lines, thus disabling perforation skip. This results in continuous printout, unless the software used in the computer defines the form length by counting the printed lines.

Values for n are valid for a line length of 8 inch (80 columns printer) or 13.6 inch (136 columns printer) set in the menu.

The absolute margin position depends on whether enlarged print mode, compressed print mode, Pica or Elite are selected. When using proportional spacing, the setting of the margins corresponds to the setting when in Pica font type (10 cpi).

The command for setting the margins must be given at the beginning of a line, all data of the same line are lost in the print buffer.

Justification and Centering

ESC a

Data Structure

Description

ASCII ESC "a" <n> hex. 1B 61 <n> or n dec. 27 97 <n> or n

In some cases it is necessary to center headlines or to have the text printed in a way that left or right margin or both margins are justified. By means of this code sequence the printer automatically justifies the text.

Justification mode depends on the value selected for n:

0 (hex.00 or hex.30) left justification (default setting) 1 (hex.01 or hex.31) centered 2 (hex.02 or hex.32) right justification 3 (hex.03 or hex.33) left and right justification

The justification mode must always be set at beginning of the line. Justification mode can be used in all print qualities.

If left and right justification is activated, the validity of codes ESC $, ESC\ and HT at

➊

the beginning of the line is checked. Left and right justification is only achieved if the length of the data line (measured from the start of data input up to a CR or LF code) fills 75% to 125% of the given printed area. At less than 75%, left and right justification justification is not achieved. If the length of the printed line extends more than 25% outside of the printed area, left and right justification justification is carried out for the character spacing which comes closest to the value of 100% within the printed area. The remaining data are printed in the next line.
