Solving printing problems
This section provides solutions to common printing problems.
If none of the following solutions work, the problem is likely caused by the
inability of the software program to properly interpret print settings. Check the
release notes on the Starter CD for known software conflicts. Otherwise, check
your software program manual, or call the software manufacturer for more
specific help with the problem.

If you are using a parallel or USB cable, make sure your printer is
