When you run this program it will print 150 lines right down the page and across the perforations. When it’s done line 110 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 top and bottom margins 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.)

201 Leave 6 blank lines at the bottom of page

30LPRINT CHR$(27);"N";CHR$(6);

40' Start top of page at line 6

50LPRINT CHR$(27);"r";CHR$(6);

100LPRINT CHR$(27) poff; I clear top and bottom margins

Now when you run the program, your printer skip the first six lines and the last six lines on each page. Always send a form feed after setting the top margin, or it will not work on the first page printed. That’s because the top margin only takes effect after a form feed.

Line 50 sets the top margin, line 30 sets the bottom margin, and line 100 clears both margins when we are done.
