Here is the way to adjust the width when it is the only problem. Tell the computer that the print line is wider than 80 characters with this WIDTH statement:

WIDTH "LPTl:", 255

The 255 is a special number that prevents the computer system from inserting a CR-LF into the line-unless, of course, there’s one in your program.

The extra line feed—CHR$(l0)—that accompanies each carriage return—CHR$(13)—d oes not cause a problem unless you need to use CHR$(13) in a graphics program. Getting rid of the extra CHR$(l0) is rather complicated. First you open the printer as a random file:

OPEN "LPTl:" AS #l

Although this allows you to send any code to the printer, you can no longer use the LPRINT command. Instead, you must use a PRINT #1 command:

PRINT #l, "Now I can print anything”

This does allow you to print anything, but it ignores any previous WIDTH statement.

If you want to print more than 80 characters per line in a graphics program, you must change your opening statement to include the appropriate WIDTH statement:

OPEN "LPTl:" AS #l : WIDTH #l, 255

And for the programs in this manual, don’t forget to use PRINT #l wherever you see LPRINT

Maintaining Your Printer

Always keep the printer in a clean and safe place. Keep it away from dust, grease, moisture and any source of heat, including direct sunlight. A safe temperature range is 40° F to 95° F (5” C to 35° C).

If the outer case is dirty, clean it with a soft, clean cloth dampened with mild detergent dissolved in water. Keep the printer lid in place to prevent any water from getting inside the printer. Do not use a hard
