Determine if there is any problem with the document file
If unknown characters and letters are printed only for a specific
document file, then the problem may exist within that file, or the
software application that you are using. In this case, try typing the same
text in a newly created file, and if the new document prints normally
then the problem exists in the original document file. If the same
problem occurs with the new file, call for service.
Determine if the printer driver has been installed properly
There may be a problem with the printer driver. Uninstall it and install
the printer driver again.
The problem may exist within the printer driver. Uninstall the printer
driver and reinstall it. For details about uninstalling the printer driver,

Determine if any special extension files or control panel
options are in use
The printer driver could conflict with a non-Apple generated file
extension or a control panel option. Use the Extensions Manager to
change the configuration to eliminate any conflicts.
