Printing with the serial interface
Problem
Recommendation
The printer cannot print
at all. Your PC shows
the following error
message:
'There was an error
writing to LPT1: (or
BRUSB) for the printer.'
■
Check that the printer cable is not damaged or
broken.
■
If you have an interface-switching device, make sure
that you choose the correct printer.
Problem
Recommendation
Cannot print from
application software.
■
If you are using a serial interface, make sure that the
slide switch of the serial interface is in the correct
position. Make sure that the interface settings have
been properly set up in the INTERFACE menu using
the control panel.
(For connecting using the
RS-232C interface only)
The printer prints the first
couple of pages correctly
but some following pages
have text missing.
■
This problem is usually related to serial interface
settings. Your computer is not recognizing the printer
input buffer's full signal. This could be caused by a
wrong serial cable connection (cable is not wired
properly or is too long) or a wrong setup of your
computer serial interface.
