If an infrared printer doesn’t print
• If you’re printing to an infrared printer, make sure its port is set to LPT3 (not
LPT1). Check the printer’s settings. You can also try using COM4 instead.
• Start Infrared Monitor before you print.
• In the Printers window, select the printer and make sure Work Offline is not
marked in the File menu.
• In Windows Help, use the Print Troubleshooter.
• For infrared printing from an MS-DOS program, run the program in an MS-DOS
window instead of in MS-DOS mode.
• Make sure the infrared light path is not blocked.
• Move the devices to within about 1/2 meter (1.5 feet).
• Make sure Windows is running—infrared printing is supported only while
Windows is running.
• Make sure the infrared printer is IrDA compatible.
• Make sure you have not disabled IrDA support on your OmniBook.
If a parallel printer doesn’t print
• In the Printers window, select the printer and make sure Work Offline is not
marked in the File menu.
• Make sure the printer port and the audio port do not use the same interrupt
value.
If the left edge of printed output is missing
• If the printer you’re 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.
Memory Problems
If a message says you’re out of memory
To find out how much memory is in your OmniBook, run HP User Tools.
• In Windows Help, use the memory troubleshooter.
• If you’re having memory problems running MS-DOS programs, in Windows Help
use the MS-DOS troubleshooter.
Mouse Problems
If the pointer is difficult to control
• Adjust the pointer settings using the Mouse icon in Control Panel.
