The printer doesn't print.
Check that the printer is connected to a working electrical outlet
and is turned on.
Check that the printer has plenty of paper. Some printers won't
start printing when there are just two or three sheets of paper left in
the tray.
Make sure the printer cable is firmly attached to both the computer
and the printer.
Make sure the Parallel Port Mode option in Hardware Setup is set
correctly for your printer. If your printer is ECP-compatible, this
option should be set to ECP. If your printer is not ECP-compatible,
this option should be set to Std. Bi-Direct.
If your printer is ECP- or IEEE 1284-compliant, make sure you
have an IEEE 1284 printer cable.
Run the printer's self test to check for any problem with the printer
itself.
Make sure you installed the proper printer drivers.
You may have connected the printer while the computer was
turned on. Turn off the computer, and turn off the printer. Turn the
printer back on, make sure it's ready (on line), then turn the
computer back on.
The printer doesn't print what I see on the screen.
Many programs display information on the screen differently from
the way they print it. See if your program has a print preview
mode. This mode lets you see your work exactly as it will print.
Contact the software manufacturer for more information.
