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 "*" command 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.
