The extra line feed character is usually no problem, unless you want
to send ASCII code 13 on its own as part of a graphics statement or a
character definition. To do this, use the OPEN statement to assign a file
number to the printer (LPTl:) and use the PRINT# statement in place of
LPRINT You also need to use a slightly different WIDTH statement. To
prepare the printer in this way use a line like this:
A third problem exists with IBM PC BASIC release 2.0. This version
cannot send ASCII code 26 (1A hex) either with LPRINT or with
PRINT #. Try to avoid including this code in your programs.
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 dust cover in place to
prevent any water from getting inside the printer. Do not use a hard
brush or cloth, and never use alcohol or a thinner to clean the printer
because it could damage the print head and the case.
Do not spray the inside of the printer with oil: unsuitable oils can
damage the mechanism. If lubrication is needed, contact your Epson
Be particularly careful with the print head. Never move it when the
printer is turned on. When the printer is printing, the print head
becomes hot. If you need to change the ribbon or load continuous
paper, turn the printer off and wait for a few minutes while the print
head cools down.
The print head should last for about 100 million characters (assuming
an average of 14 dots per character). When it fails, one or more of the
pins may fire erratically or stop firing completely making the printout
