printer won't print

I have a lexmark printer/fax/scanner. It will fax out and recieve faxes and print the faxes but it will not print from command from the computer. I have tried different usb ports and restarted my computer several times. the printer icon sayes it is printing but it never starts printing. any suggestions

Find the correct drivers for your printer here and reinstall them and hopefully this will sort out the problem. You may not have the latest drivers.
