Appendix A LQ-1500 Command Summary This appendix gives a brief summary of the LQ-1500 commands (control codes). While this is a complete list of the commands, the descriptions are not complete in all cases. The complete descriptions of all the commands, including examples of their use, can be found in the LQ-1500 Programmer's Manual. In some cases the explanations given here describe the apparent function of the commands, rather than the actual mechanical movements of the printer. For example, since the printer prints in both directions, the line feed command may not actually return the print head to the left margin if the next line prints from right to left, but the final effect on the printed page is the same as if it had. The commands are organized into five logical groups: Vertical Spacing Commands, Horizontal Spacing Commands, Character Set Commands, Graphics Set Commands, and Miscellaneous Commands. The function is what the printer will do when given the proper command. The format is the correct syntax for the ASCII code that the printer undertands. This code may expressed as a symbol, a decimal value, or a hexadecimal value depending on the program you are using. Where n (or another italic letter) is used as a variable, it stands for a numerical value. 49

Appendix A
LQ-1500 Command Summary
This appendix gives a brief summary of the
LQ-1500
commands
(control codes). While this is a complete list of the commands, the
descriptions are not complete in all cases. The complete descriptions
of all the commands, including examples of their use, can be found in
the
LQ-1500 Programmer’s Manual.
In some cases the explanations given here describe the apparent
function of the commands, rather than the actual mechanical move-
ments of the printer. For example, since the printer prints in both
directions, the line feed command may not actually return the print
head to the left margin if the next line prints from right to left, but the
final effect on the printed page is the same as if it had.
The commands are organized into five logical groups: Vertical
Spacing Commands, Horizontal Spacing Commands, Character Set
Commands, Graphics Set Commands, and Miscellaneous Com-
mands. The
function
is what the printer will do when given the proper
command. The
format
is the correct syntax for the ASCII code that
the printer undertands. This code may expressed as a symbol, a
deci-
mal value, or a
hexadecimal
value depending on the program you are
using. Where n (or another italic letter) is used as a variable, it stands
for a numerical value.
