When you are using your printer with the DIP switch 2-2 off,
the (ESC)"A"CHR$(
) n works
to change
the line spacing
without (ESC)"2".
So in this case, change the following lines as
shown below:
40 LPRINT CHR$(27);"A";CHR$(I);
80 LPRINT CHR$(27);"2"
The results are the same as previous one.
You may wonder why they picked l/60 of an inch as the incre-
ment for the line spacing command. There's a good reason: the
dots that the printer makes are l/l80 inch apart. So this means
that you can vary the line spacing in increments
as fine as three
dots -
unless you want finer spacing, like one dot spacing.
The (ESC)"3"CHR$(n)
command sets the line spacing in in-
crements of l/180 inch. Change line 40 in your program so it is
like this:
40 LPRINT CHR$(27):"3";CHR$(I);
and run the program again. Now the results will look like this:
.
INCH.
The program works just the same as before, but the line spac-
ing are just one-third what they were. This is because (ESC)"3"
CHR$(n) sets the line spacing to n/180 inch.
Table 6-2 shows all the line spacing commands,
including
several "shortcut" commands for commonly used line spacings.
