Let’s set up a 7 inch high form length, which is typical of
many computer checks. The following program will do it.
NEW
10 ' Demo of variable form lengths
20 LPRINT CHR$(27);"C";CHR$(O);CHR$(7);
30 LPRINT "PAY TO THE ORDER OF:"
40 LPRINT CHR$(lZ);
50 LPRINT "PAY TO THE ORDER OF:"
60 END
This program should print “PAY TO THE ORDER OF:”
twice, and they should be 7 inches apart. Line 20 sets the form
length to 7 inches. After line 30 prints, line 40 sends a form feed
advance the paper to the top of the next form. Line 50 then
prints its message.
After you have run this program, turn off the printer and ad-
just the top of form position. When you turn the printer back on
the page length will reset to its normal setting (usually 11
inches).
TOP AND BOTTOM MARGINS
Some programs don’t keep track of where they are printing on
the page. This causes problems when you get to the bottom of a
page because these programs just keep on printing, right over
the perforation. This makes it very hard to read, especially if a
line happens to fall right on the perforation.
The printer has a solution to this predicament. This printer
can keep track of the position on the page, and advance the
paper so that you won’t print too near the perforation. There are
two commands to do this. One controls the space at the top of
the page (top margin) and the other controls the space at the bot-
tom of the page (bottom margin). The control codes are given in
the following table:
