With no more information than you gave (we really need the Model of Printer & Computer basic specs) my guess is that you have the wrong setting in your BIOS for the type printer you have. If you have never gone into the BIOS settings before, you might want to get someone to help you. Typically to get into bios, type DELETE key as the computer begins to count RAM after you turn it on. A SETUP screen will appear (usually Blue in color) ....one of the Selections is "Integrated Peripherals" or something that includes peripherals in it.......go to the settings related to "Printer"......change to ECP or Normal ...if already ECP, change to SPP and save and restart the computer........then try the printer again. If that doesnt do it.....your printer drivers are not in correct or you may have a defective printer....in any case, you will then need a technician to get it going.
