Command Summary 9-1
Using the Command Summary
This chapter lists and describes all the commands available on the
LQ-510.
The first part of this chapter lists all commands in numerical order and gives the number of the page where each is fully described. If you know which command you are looking for, consult the numerical list.
Note: The Quick Reference card at the end of the book also contains a list of the commands divided by topic, with page number references that direct you to full explanations of the commands.
The second part of this chapter lists and describes each command separately; the commands are divided into the following subjects:
Printer operation
MSB control
Data control
Vertical motion
Horizontal motion
Overall printing style
Print size and character width
Print enhancement
Word processing
Character sets
User-defined characters
Graphics
Each command description has a format section and a comment section. The format section gives the ASCII, decimal, and hexadecimal values for the command. These three formats are equivalent, and it should be easy to pick the one most suited to your purpose. The comment section describes the effect of the command and gives any additional information necessary for using it.
Note: Some application programs use control key sequences. See the Control Key chart on page 9-4.
9-2 Command Summary
Using the Command Summary
The simplest type of command consists of a single character to be sent to the printer. For instance, to print in condensed mode, the code format is:
ASCII code:
Decimal:
SI
15
H e x a d e c i m a l : 0 F
This code can be sent from a program by sending the code 15 directly.
More complex commands consist of two or more character codes.
For example, to print in double-wide mode, the code format is the following:
ASCII code:
Decimal:
ESC W n
27 87 n
Hexadecimal: 1B 57 n
In this case n can be either 1 (on) or 0 (off), to begin or end doublewide printing. You can use either of the following commands to turn on double-wide print from BASIC:
LPRINT CHR$(27);CHR$(87);CHR$(l)
LPRINT CHR$(27);"W";CHR$(l)
For the following commands that use only 0 or 1 for the variable, either the decimal or hexadecimal values 1 and 0 or the ASCII characters 1 and 0 can be used:
ESC U, ESC x, ESC p, ESC W, ESC S, ESC -, and ESC %
For example, in BASIC you can turn on proportional spacing with either of these statements:
LPRINT CHR$(27);"p";CHR$(l)
LPRINT CHRS(27);"p";"l"

Control Key Chart
Some application programs use control key codes for decimal values
O-27. The table below gives you the proper values. The Control Key column indicates that you press the control key at the same time you press the key for the letter or symbol in that column. For example, you press the control key and A at the same time to send the value 1.
Some application programs that use this system cannot use
Control-@, and many programs use the control keys for other purposes.

Set Right Margin
Comments:
Sets the right margin to n columns in the current character size.
Settings made in the proportional mode are treated as 10 cpi. This command clears previous tab settings and all previous characters in the print line. The minimum space between the margins is the width of one double-wide 10 cpi character.

Hexadecimal: 1B 24 n1 n2
Comments:
This sequence specifies the distance from the current left margin that subsequent characters are to be printed, using this formula: total number of dots = n1 + (n2 x 256). Each unit equals 1/60th of an inch. The sequence is ignored and the previous setting remains effective if the position specified is beyond the right margin.

Decimal:
ESC \ n1 n2
27 92 n1 n2
Hexadecimal: 1B 5C n1 n2
Comments:
Determines the position (relative to the current position) at which printing of subsequent data will start. To find n1 and n2, first calculate the displacement required in dots. If the displacement is to the left, subtract it from 65536. Send the resulting number using this formula: total number of dots = n1 + (256 x n2). The command is ignored if it would move the print position outside the current margins. A unit is 1/120th of an inch in draft, and
1/180th of an inch in Letter Quality or proportional modes.

This command allows setting of up to 32 horizontal tabs, which are entered as n1, n2, n3, etc., (from 1 to 255) with the number 0 character terminating the command. The tab settings must be entered in ascending order. ESC D 0 clears all tabs. The default settings, when power is turned on or after an ESC @ command, are at every eight characters. The tab settings are not affected by changes in cpi. The tab positions in proportional printing are determined by the 10 cpi character size.

Turns proportional mode on and off.
The following values can be used for n:

The width of proportional characters varies from character to character. Therefore, a narrow letter like i receives less space than a wide letter like W. Proportional character widths are given in the Appendix. This command overrides the condensed mode and fixed cpi fonts. When proportional is cancelled, the previously selected font is used. Graphic characters are printed in fixed cpi only; proportional mode is only available in Roman and Sans
