The printer prints unexpectedly or it prints garbage.

Make sure that the printer cable is not too long. We recommend that you use a parallel or USB cable that is no longer than 2 meters (6.5 feet).
Make sure that the printer cable is not damaged or broken.
If you are using an interface-switching device, remove it. Connect your computer directly to your printer, and then try again.
Make sure that you have chosen the proper printer driver with 'Set as Default'.
Make sure that the printer is not connected to the same port that is also connected to a storage device or scanner. Take away all other devices and connect the port only to the printer.
Turn off the Status Monitor in the Device Options tab in the Windows® printer driver.(if applicable)
