LQ-1600K Emulation

“Emulation” refers to the ability of a printer to execute the commands of other printer control languages. In LQ-1600K emulation mode, your printer prints files coded for Epson LQ series printers, particularly the LQ-1600K.

Exceptions And Differences

Because Of Mechanical Differences Between Your Printer (A Line Matrix Printer) And Moving Printhead Serial Matrix Printers, Some Features Are Approximated Or Not Supported.

Commands not supported by our printer:

1. Control paper loading/ejecting (ESC EM n)

2. Select user-defined set (ESC % n)

3. Define user-defined characters (ESC k NUL

4. Copy ROM to RAM (ESC : NUL

5. Select justification (ESC

6. Set MSB to 1 (ESC >)

Epson Character Sets

The LQ-1600K printer uses two character sets: the IBM PC set and the Epson set. The Epson set is the ASCII character set with the upper, non-ASCII set defined as italics and the usually unprintable codes designed as international characters. (See

Table 3.)

Chapter 2 LQ-1600K Emulation

Escape Sequences

Some LQ-1600K control codes consisting of more than one character are called escape sequences because the first character in the sequence is the ASCII ESCape character. ESC alerts the printer that a special function command—not printable characters—follows.

The format for an escape sequence is:

ESC (parameter 1)(parameter 2)...(parameter n)

For example, to select emphasized (offset) print, send the ESC character immediately followed by the E character (do not add a space character):

ASCII: ESC E Hex: 1B 45Dec: 27 69

FS Sequences

Another type of control code which consists of more than one character is called an “FS sequence,” because the first character is the ASCII FS character. This control code is used when the printer is printing Double Byte Character Set (DBCS) characters. The FS alerts the printer that a special function command (not printable characters) follows. Most FS commands work only on DBCS characters.

The format for an FS sequence is:

FS (parameter 1)(parameter 2)...(parameter n)

For example, to rotate DBCS characters by 90° counter-clockwise, send an FS character immediately followed by the J character:

ASCII: FS J Hex: 1C 4ADec: 28 74

Super-Set Commands

The unique control code sequence for both SSCC and ASSC commands are defined in the table below:

Control

Code

SSCC ESC | } ; 1B 7C 7D 3B 27 124 125 59

ASSC ESC | } ; q 1B 7C 7D 3B 71 27 124 125 59 113

ASCII Value Hex Value Dec Value

Set And Reset Codes

Set and reset are other ways of saying turn on and “turn off; select and deselect; or enable” and disable.”

Some printer features are set and reset with an escape sequence and the numbers 1 or 0. In those cases you can represent 1 and 0 as hexadecimal codes 01 and 00 or as the ASCII codes for the numerals 1 and 0 (hexadecimal 31 and 30).

DBCS Mode

When the printer is in DBCS mode, it can print double byte characters— characters that require two bytes to define. It can also print a limited number of single byte ASCII characters. If a form hex 0x20 through hex 0x7F is sent to the printer, it will be printed as a standard ASCII character. If a character is larger that 0x7F, it will be combined with the next character to produce one DBCS character.

DBCS characters are only available in the LQ, Near LQ, Normal, Hi-Speed, Super Hi-Speed, and Ultra Hi-Speed typefaces. The command to select DBCS mode (FS &) switches the printer to one of these typefaces. Near LQ is the default typeface, but if another print quality has been selected previously through the FS x command, then that print quality is the DBCS typeface selected.

The character printed when the printer combines two characters into one double byte character depends on the character set of your particular printer.

Configuring The LQ-1600K Emulation With Control Codes

The remainder of this chapter describes the LQ-1600K printer control language codes that may be sent from a host computer attached to the printer in order to invoke and configure numerous LQ-1600K emulation functions.

Format For Control Code Descriptions

The following information is listed for each code (where applicable and possible) in this chapter:

ASCII Mnemonic. The ASCII name for the control code. Hex Code. The hexadecimal equivalent of the code. (For octal equivalents,

refer to Appendix A.)

Dec Code. The decimal equivalent of the code. Purpose. The function(s) of the control code. Expression. The control codes used in the BASIC programming language. Comment. A description of exceptions or limitations to normal use. Example. A sample expression written in the BASIC programming language

is provided for some control codes to illustrate how the code is used.

Chapter 2 Configuring The LQ-1600K Emulation With Control Codes

Align Two Half-Width Rotated Characters In DBCS Mode

ASCII Code FS D Hex Code 1C 44 Dec Code 28 68 Purpose Aligns two half-width rotated characters to fit the space

occupied by a normal size rotated character.

Comment Right after the control code sequence, two characters are

paired. The characters are not required to be half-width to be aligned, because the command automatically takes care of that. It is only necessary for the characters to be rotated in order for the command to take effect. Only two characters are combined at a time.

This command does not function while in non-DBCS mode.

Example The following program demonstrates the function of the

command.

Backspace

ASCII Code BS Hex Code 08 Dec Code 08 Purpose Moves the simulated print head to the left, one-byte space

toward the first character column. In DBCS mode, the movement is two one-byte spaces.

Comment Moves the character position indicator one-byte space (two

one-byte spaces in DBCS mode) to the left at the current character pitch setting. The code is ignored if the simulated print head is positioned at the first character column.

Example Print and send two backspaces in ASCII and DBCS mode.

does not function while in non-DBCS mode.

Chapter 2 Configuring The LQ-1600K Emulation With Control Codes

Cancel Line

ASCII Code CAN Hex Code 18 Dec Code 24 Purpose Clears all data not yet printed from a line, but does not affect

control codes.

Comment You can use this control code to delete a line, but do so with

caution to avoid possible misprinting. This control code cancels the double wide attribute set by SO. No other print attributes are affected. The simulated print head goes to the print position it had after the last CR or paper motion command.

Cancel Spacing Adjustment

ASCII Code FS V Hex Code 1C 56 Dec Code 28 86 Purpose Cancels the spacing adjustment of half-width characters to fit

into the full-width DBCS character space.

Comment This command cancels the effect of FS U. This control code

does not function while in non-DBCS mode.

Carriage Return

ASCII Code CR Hex Code 0D Dec Code 13 Purpose Returns the simulated print head to the left margin. Comment The CR code may or may not cause printing or paper motion,

depending on the configuration as set from the control panel. If CR=CR is set, the characters following the CR are printed over the previous characters on the line. If CR=CR+LF is set, the paper is also moved one line at the current line spacing. This automatic LF will also cancel all single line print attributes.

mode. This command affects the front panel setting of cpi.

Condensed Print (Set/Reset)

ASCII Code SI ESC SIDC2 Hex Code 0F 1B 0F18 Dec Code 15 27 1512 Purpose Condenses print pitch as close as possible to 60 percent of the

former character width.

Comment 10 cpi condenses to 17.1 cpi

12 cpi or 13.3 cpi condenses to 20 cpi 15 cpi will not have condense print

Control code SI affects all subsequent characters. After receiving code SI, all characters are printed condensed until the printer is reset by ESC M, ESC P, DC2, a printer reset, or a new print mode control code. SI code (hex 0F) is equivalent to the ESC SI code. If condensed print is not allowed in the current font, this code is ignored. Proportional spacing overrides condensed printing. This control code does not function while in DBCS mode. 12 cpi will condense to 20 cpi

only

if the menu option “20 CPI Condensed” is enabled.

Example The program below shows condensed character printing and

reset.

DBCS Mode (Select)

ASCII Code FS & Hex Code 1C 26 Dec Code 28 38 Purpose Places the printer in DBCS mode. Comment All data received by the printer with the MSB set will be paired

with the next character which may or may not be a DBCS character. If the pair constitutes a 2-byte code which falls within the defined DBCS character set range, a DBCS character will be printed. Otherwise, the characters will be treated individually and printed accordingly. Control codes which normally can be applied to a non-DBCS mode typeface will not have an effect.

This command will set the DBCS/ASCII mode in the front panel to DBCS mode.

DBCS Mode (Cancel)

ASCII Code FS . Hex Code 1C 2E Dec Code 28 46 Purpose Cancels the effect of the FS & command and places the printer

in single-byte character mode (ASCII). The typeface will remain the same.

selected; no characters are defined for these codes in the italic character table.

Font Expansion

ASCII Code ASSC 0 e n1 n2 Hex Code ASSC 30 65 n1 n2 Dec Code ASSC 48 101 n1 n2 Purpose Expand the DBCS characters up to the size of 72.

For this command to work, n1 must be the same value as n2 (i.e. n1=n2). When n1 and n2 = 25 to 72, this set font expansion mode is ON. The value of n1 and n2 determines the bitmap size. For example, if the size of n1 is 50, then the size of the bitmap will be set to 50x50. For n1 and n2 = 24, the font expansion mode resets to OFF and the bitmap size reverts to the default, 24x24.

Inter-line spacing and inter-character spacing calculations are based on standard setting as if the bitmap is 24x24. This command only increases the size of the bitmap and does not affect the inter-character spacing or inter-line spacing. For example, if inter-line spacing is 6 dot rows, when the bitmap is expanded from 24x24 to 72x72, the inter-line spacing still remains as 6 dot rows. The same is true for inter-character spacing.

Other commands, such as double height, double width, 2x2 times, left/right margin etc., will not function when the font expansion mode is set on. For different typefaces, the characters will expand based on the appropriate typeface resolution. All commands affecting LPI and CPI still takes effect and is set as if the bitmap is 24x24 as mentioned above.

Where n1 = 24 - 71 n2 = 24 - 72

character position a distance of one line at the current line spacing.

Comment If configured for LF equals newline (LF=CR+LF), the simulated

print head is moved to the left margin, otherwise it is not moved from its current position. The current line is printed, and the simulated printhead moves down a distance equal to the current line spacing. If there are no dots, the paper is moved but no printing occurs. When possible, successive line feeds are accumulated and moved at once. The amount of paper advanced by the LF code can be set by any of the line spacing control codes: ESC 0, ESC 2, ESC 3, ESC A, or ESC +.

This code cancels all single line print attributes such as double high and double wide characters.

Appendix A

B Vertical Page Formatting

Overview

Rapid vertical paper movement is called slewing. You can enable the printer to slew paper to preset locations on a page by loading the vertical tab table.

The vertical tab table is a set of programmed vertical tabs. Various lines of the form are assigned vertical tabs, which are then accessed by control codes for rapid paper advancement to the tab position.

Two control codes are used for vertical tabbing: ESC B sets single channel vertical tabs, and VT executes a vertical tab. These codes are described in Chapter 3. The Epson emulation also has ESC / to select one of eight tab channels and ESC b to set the tabs in a particular channel.

Executing Vertical Tabs

The vertical tab execute code is VT (hex 0B). It prints the contents of the print buffer (if data are in the buffer) and causes paper movement to the next predefined vertical tab position. If a tab position is not defined, the paper is moved to the next line at the current line spacing. If a tab position is at the current line, the paper is moved to the next tab position. If no tab positions are defined between the current line and the end of the form, the paper moves to the next TOF.

Appendix B Overview

Vertical Tab Positions

Vertical tab positions are set by line number. A maximum of 16 vertical tab positions can be set on the form. A sample format is shown in

The first vertical tab is set at line 6 for part number data, a second tab is set at line 8 for part name data, and a third tab is set at line 14 for quantity data. The ESC B code assigns the vertical tabs to the lines of the form. Once the tab positions are set, sending the vertical tab execute code (VT) causes the paper (currently at the top-of-form position) to advance to the first tab position for PART NUMBER data. Sending another VT moves the paper to the second tab position for PART NAME, followed by a third VT to access the third tab position for QUANTITY data.

Bit Image Graphics

Bit image graphics are created by vertically printing the bit pattern of a series of data bytes. For example, the bit pattern of the ASCII character A (hex 41, decimal 65) is shown in clockwise, we have a vertical data byte with the most significant bit (MSB) at the top. If we then print each 1 (true) bit as a dot, the result is a “bit image” plot of the ASCII character A.

Appendix C Bit Image Graphics

The relationship between the ASCII character, its decimal value, and its bit image plot is shown in but some fonts have taller and shorter characters. (You may have to adjust the line spacing in order to print without horizontal gaps.) Data bytes are identified by their binary, octal, hexadecimal, or decimal equivalents. These numeric equivalents are combined in data streams to form graphic patterns such as the one illustrated in

Figure 4. All 8 bits of the data byte are used in all fonts,

Figure 4. Bit Image Pattern from an ASCII Character

Bit image plotting is not limited to printable ASCII characters. You can print bit image patterns for any 8-bit data byte with decimal values ranging from 0 through 255 (hex 00 through hex FF). (The ASCII character set is charted in Appendix A.)

Designing a Bit Image Pattern

A bit image pattern is produced in four steps:

1. On a quadrille pad or graph paper, lay out the graphic pattern you want to print. (See

2. Determine the decimal equivalent of each vertical data byte in your pattern. (The sum of the decimal equivalent of each true bit in the vertical data byte is the decimal equivalent of the data byte.)

3. Write a program to generate the pattern.

4. Enter and run the program on the host computer.

Bit Image Density

You can print bit image graphics in different dot densities. Select dot densities by sending a control code in the data stream.

NOTE: Every line of graphics data must include the necessary bit image

command so the printer can perform the chosen graphics functions.

Single Density Mode: ESC K

Single density mode selects normal density bit image graphics of 60 dpi horizontally and 72 dpi vertically.

Appendix C Bit Image Graphics

Double Density Mode: ESC L

Double density mode prints up to twice the number of dots per inch horizontally in the same space used for single density. The vertical dot density remains the same as in single density mode. Double horizontal density requires twice the number of input data bytes to print the same length line as single density. Printing double density reduces the printing speed by half.

Double Speed-Double Density Mode: ESC Y

When the double density-double speed control code is received, data bytes print at double the current horizontal dot density, but adjacent dots are not printed. Since double density graphics are printed at half speed, double speed-double density graphics are printed at the same speed as single density graphics. This mode is often used to position a simulated print head precisely by sending blank dot columns.

Quadruple Density Mode: ESC Z

When printing quadruple density graphics, the printer combines adjacent quadruple density bit image bytes. The compounded data are then printed in double density mode.

Bit Image Programming Format

The bit image command format is:

ESC CC (n1) (n2) where: ESCthe escape sequence control code

bar code A printed code consisting of parallel bars of varied width

and spacing and designed to be read by a onedimensional scanning device.

baud A unit of speed that measures the rate at which

information is transferred. Baud rate is the reciprocal of the length in seconds of the shortest pulse used to carry data. For example, a system in which the shortest pulse is 1/1200 second operates at 1200 baud. On RS-232 serial lines, the baud rate equals the data flow rate in bits per second (bps). To communicate properly, a printer must be configured to operate at the same baud rate as its host computer.
