Individual graphics options commands
As previously mentioned, the LQ responds to commands that are
used by Epson FX and RX series printers. There are four individual
graphics options commands that are very much the same as the
ESCape
“*” command, but each one works for only one graphics
option. All these commands are 8-pin graphics options. Note that
these commands contain one less variable than the ESCape "*" comm-
and because they don’t need to select a graphics option. They are
shown in Table
6-2.

Reassigning command
The LQ has a command that allows you to change the graphics
option assigned to any of the four individual graphics options com-
mands. The command looks like this:
ESCape “?”
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 (from Table
6-1)
that you want to assign to it. For example, to
change the ESCape “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.
