Welcome to the Windows 7 Forums oneerc
I have to agree with Gary. A clean install would be your best choice. Many people have large external USB drives, I would backup all important data, boot from the Windows 7 7000 disk, and use the advanced options to format the destination drive. If your printer drivers worked ok with Vista, they should work ok with Windows 7. (should) I've only found 1 in 20 programs that didn't run in Windows 7.
Let us know how it goes.
