■Changing the page length

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 commands for doing this, shown in this table.

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).
