Serial, Parallel, And Usb Problems - HP OmniBook 4100 User Manual

For most printing problems, use the Print Troubleshooter in Windows Help.
If a serial or parallel printer doesn't print
Check that you are using a proper cable or cable adapter, and that the printer is
on.
Check for paper in the printer or other printer errors.
Make sure the printer cable is secure at both ends.
If an infrared printer doesn't print
Windows NT 4.0 does not support infrared devices.
Make sure the infrared light path is not blocked.
Check for paper in the printer or other printer errors.
Make sure Windows is running—infrared printing is supported only while
Windows is running.
An infrared driver must be installed and the BIOS Setup setting must be
enabled. For details, refer to the driver's Readme file (located in
\Omnibook\Drivers).
In Windows Help, use the Print Troubleshooter.
If the left edge of printed output is missing
If the printer you are using is a 600-dpi (dots per inch) printer, try selecting a
compatible printer driver for a 300-dpi printer. For example, for a 600-dpi
HP LaserJet printer, try using the HP LaserJet IIIsi driver (300-dpi). Certain
applications may not work properly with 600-dpi printers.
