The net addition to the program cancels elite with ESCape “P”
(ASCII 18 in Proprinter mode) and turns on condensed with ASCII
15:
30
LPRINT CHR$(27)"P"CHR$(15);
or
30
LPRINT CHR$(18)CHR$(15);
Now run the program to see the line printed in condensed mode.
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_'abcdefghi
Cancelling Codes
As you saw in the third version of the print width program, you
must cancel a code when you don’t want it any more. With very few
exceptions, the FX-286 modes stay on until they are cancelled. It is
important to remember this because an FX-286 mode can stay on even
if you change from BASIC to another type of software. For example,
if you run the above program and print a memo with a word process-
ing program afterward, the memo is printed in condensed because the
printer is still in condensed mode. To cancel condensed, use ASCII 18.
In BASIC, you use this format:
LPRINT CHR$(18)
To avoid having one program interfere with the printing modes of
another, you can cancel a mode one of two ways:
l
With a specific cancelling code such as ASCII 18 to cancel con-
densed. Each mode has a cancelling code, which you can find in the
discussion of the code and in Appendixes G and J. Pica is an excep-
tion to this rule. To cancel pica, turn on elite or condensed.
l
By resetting the printer, a method explained in the next section.
Resetting the Printer
Resetting your FX-286 cancels all modes that are turned on. You can
reset the printer with one of two methods:
l
In the Epson mode only, by sending the reset code (Escape "@")
l
Turning the printer off and then on.
