hi first of two questions you say your running windows7 ultimate what version is it 64 bit or 32 bit
if its 64 bit thats easy try typing in the model of your printer followed by 64 bit drives
ie
hp scanjet 3770 64 bit drivers
once you install the main driver then put your original cd that came with your printer in the drive and right click and go explore and install each part that you wish to use
or run the disc as normal and insted of clicking simple setup click advanced options and install each feature
cheers hope ya have some luck
