printer driver. Or, for Windows or Macintosh, uninstall the printer driver and reinstall

b. If the page does not print, then the problem is with the computer or the program.

not work (the document does not print) complete these steps:

b. If you connected the MFP to the network, connect the MFP directly to a computer
with a parallel cable. Redirect the MFP to the correct port, or reinstall the software,
selecting the new connection type that you are using.
