Individual Graphics Options Commands

As previously mentioned, Epson printers are upward compati- ble. Therefore the SQ-2000 responds to commands that are also used with Epson FX and RX series printers. There are four individual graphics options commands that act very much the same as the <ESC> “*” command, but each one works for only one graphics option. Note that these commands contain one less variable than the <ESC> “*” command because they don’t need to select a graphics option. They are shown in Table 6-2.

Assigning Graphics Options

The SQ-2000 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

Where s is the letter that represents the command that you wish to change the assignment for (i.e., K, L, Y, or Z) and m is the number of the graphics option (from Table 5-1) that you want to assign to it. For example, to change the <ESC> “K” command to use the QX-10 CRT screen graphics option, the command would look like this:

<ESC> “?" “K” 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. However, you should make this change with caution.

If you change one of the 8-dot graphics options to a 24-dot graphics option without changing the program that supplies the graphics data, you will print garbage (if the program prints at all). Remember, the 24-dot graphics options require three times as much graphics data as the 8-dot graphics options. Moreover, the data is arranged differently.
