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 indi-
vidual 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 vari-
able than the <ESC> “*” command because they don’t need to
select a graphics option. They are shown in Table 6-2.
Table 6-2. Individual graphics options commands
Command
Function <ESC> "*" Format
<ESC> "K"
Single-density
<ESC> "*" n1 n2 data
<ESC> "L"
Double-density <ESC> "*" 1 n1 n2 data
<ESC> "Y" High-speed, <ESC> "*" 2 n1 n2 data
double-density
<ESC> "Z"
Quadruple-density
<ESC> "*" 3 n1 n2 data
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.
