Now run the program. You should get the results you see below,
10
pica characters per inch.

Changing Pitches
Now you can try other pitches. As we explained in Chapter 3, the
IX-86 uses the same pattern of dots for pica, elite, and condensed
characters, but it changes the horizontal spaces between the dots to
produce the three different widths.
In elite mode there are 12 characters per inch, and in condensed
there are
17.
The LX-86 prints in elite when it receives the ESCape
“M” command and prints in condensed when it receives the
ASCII
15
command. Print a sample line of elite characters by
adding this line
to
your previous program:
20 LPRINT CHR$ (27) “M” ;
This line uses the command for elite, ESCape “M”, to turn on that
mode. Your printout should look like the one below.
ABCDEFGHIJKLMNOPQRSTUVWXYZ[\lˆ_`abcdefghi
The next addition to the program cancels elite with ESCape “P” and
turns on condensed with ASCII
15:
30 LPRINT CHR$ (27) “P” CHR$ (15) ;
Now run the program to see the line printed in condensed mode.
ABCDEFHIGKLMNOPQRSTUVWXYZ[\]ˆ_`abcdefghi
Cancelling Codes
As you saw in the third version of the print pitch program, you
must cancel a code when you do not want it any more. With very
few exceptions, the LX-86 modes stay on until they are cancelled.
It is important to remember this because an
LX-86 mode can stay
on even if you change from BASIC to another type of software. For
example, if you print a memo with a word processing program
after you run the program above, the printer will still be in
condensed mode; therefore, the memo will be in condensed
print. To cancel, use ASCII
18.
