You may have some computer forms that are not 11 inches high. That’s no problem, because you can tell your printer how high the forms are that you are using. There are two ways to do this; set the Form Length switch to your form’s length before turning on the power, or use one of the two commands shown in this table.

Let’s set up a 7 inch high form length, which is typical of many computer checks. The following program will do it.

20 LPRINT CHR$(27);"C";CHR$(O);CHR$O;
30 LPRINT "PAY TO THE ORDER OF:"
40 LPRINT CHR$(12);
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.
