the operating system is window xp and 2000, it will not let me install it, since i have window 7 do i need to buy another printer, never mind i had the wronge cd in there i finally install it.

Which operating system are you trying to install to - Windows 7 or XP or 2000? If it's Windows 7, you will need to go to the HP driver support page for your printer on their website and download the updated drivers for Windows 7.

Go here and enter your printer model and number.
