Pages Don't Print - Pentax PocketJet User Manual

If you are using an optional RS-232C serial interface cable,
make sure the serial port speed on the printer and the
computer match. DIP switches 1 and 2 control the speed of
the serial port. See page 20. If the serial port speed is
correct, the serial connection may be defective. Replace
the defective part—most likely the serial interface cable.
Some characters print normally, but others
print incorrectly.
Check the printer driver you are using. Select the LaserJet IIP
printer driver, or if necessary, the LaserJet II driver. Do not
select the LaserJet IIP Plus driver.
If you are using DOS "PRINT" or "COPY" commands or a DOS
application that does not send PCL printer setup information
prior to the print job, check the settings of the DIP switches
that control the default character set. See page 26.

The green DATA indicator remains lit but
does not blink.
The print buffer contains unprinted data from the software
application. If you have already inserted paper in the
printer, press the main switch to "form feed" the incomplete
page. If paper is not inserted, insert another sheet of paper
to continue printing.
The application should be sending data to
the printer, but the green DATA indicator is
not lit.
Make sure the interface cable matches the port to which
the computer is sending the data. Use the parallel interface
cable with a parallel port and a serial interface cable with a
serial port. See page 19.
Make sure the interface cable is connected to the port to
which the computer is sending data.
If you are using a serial cable, make sure the serial port
speed on the printer and the computer match. DIP switches
1 and 2 control the speed of the serial port. See page 20.
