problems.
Print a configuration page from the printer’s control panel to
verify that the interface configurations shown on the printout
match those on the host computer. (See page 314
to print a
configuration page.)
Computer software
problem.
Check that your computer is working correctly by printing
from a software application you know works or by printing a
plain text file to see if the problem is with your software
application or printer driver. (For example, C:\dir>LPTn
where n is the number of the computer port the printer is
connected to, for example LPT1.) To output the page, you
may have to send a form feed command from your computer.
Software is selecting the
wrong port.
Check your operating system’s port settings to be sure the
print job is being sent to the correct port (for example, LPT1).
Printer port problem. Check that your computer’s port is configured and working
properly. One way to check this is to connect another printer
to that port on your computer and print an application you
know works.
