Do a search for your printer in the Windows 7 Compatibilty Center. It will tell you if your printer is supported by Windows 7. If it is, there will a direct link to the manufacturer's website for you to get the drivers you need. Before you try to install any other driver, be sure to uninstall the one you currently have. http://www.microsoft.com/windows/compatibility/windows-7/en-us/default.aspx
Hope this helps!
