Nancy, did you uninstall the old printer from Control
Panel, Add/Remove Programs? Do you have the instructions
on how to install the 612c? If so, follow the instructions
exactly. You may need an undated driver. Go to the HP
website and look for driver downloads and see if their is
on for your printer that you can download. I have one of
those printers. Maybe I can help further.
