Individual graphics option commands
There are four individual graphics option commands that are very much
the same as the ESC * command, but each one works for only one
graphics option. All these commands are for B-pin graphics options.
Note that the commands contain one less variable than the ESC *
command because they don’t need to select a graphics option.
The commands are shown below:
Because of a difference in line spacing increments, the shape of graphics
figures produced on the LQ-2550 with an B-pin option is different from
the output from the same program on a 9-pin printer.
The reassigning command
The LQ-2550 has a command that allows you to change the graphics
option assigned to any of the four individual graphics option commands.
The command looks like this:
ESC?sm
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 graphics option, the command in BASIC is:
LPRINT
CHR$(27)
;"?";"K";CHR$(1,)
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.
