Graphics
The reassigning command
The LQ has a command that allows you to change the graphics
option assigned to any of the four individual graphics options
commands. The command looks like this:
ESC ? s m
The letter s represents the command that you wish to change the
assignment for (K, L, Y, or Z) and m is the number of the graphics
option that you want to assign to it. For example, to change the
ESC K command to use the CRT I screen graphics option, the
command in BASIC is:
LPRINT CHR$(27)“?“;“K” CHR$(4)
This is a quick way to change the aspect ratio of the design that
you are printing. Changing the graphics option will change the
width without changing the height. You should, however, make this
change with caution.
If you change one of the 8-pin graphics options to a 24-pin
graphics option without changing the program that supplies the
graphics data, you will print garbage (if the program prints at all).
Remember, the 24-pin graphics options require three times as much
graphics data as the 8-pin graphics options.
