Meaningless characters are printed
Check the cable connection.
A common cause for nonsense characters is a poor cable connection between the printer
and computer.
The wrong printer might be selected.
Check to make sure your printer is selected as the current or default printer.
The document file might be damaged.
This happens occasionally. If you can print other documents from the same software
package, try to print using a backup copy of your document.
Check for conflicts with port-sharing devices.
If you are using a parallel cable, make sure your printer is connected directly to the parallel
port. Do not share the port with other devices such as a Zip drive or other printers.
The system might need to be restarted.
Turn the printer and computer off, wait a few seconds, turn them both back on, and then
try printing again.
