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.

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
