When you run this program it will print 150 lines right down the page and across the perforations. When it’s done line 90 sends a form feed to advance to the top of the next page. Look at the lines that have printed near the perforations. Separate the sheets and see if any of the lines have been torn in half. These are the problems that the bottom margin will solve.
Now add the following lines to your program. (Don’t forget the semicolons or you won’t get quite the same results that we did.)
20’ Leave 6 blank lines at the bottom of page
30LPRINT CHR$(27);"N";CHR$(6);
80LPRINT CHR$(27);"0"; ' Clear bottom margin
Now when you run the program, your printer skip the last six lines on each page.
Line 30 sets the bottom margin, and line 80 clears bottom margin when we are done.
