Actually, this page on the HP web site indicates that drivers are available via Windows Update or via download from HP. The page is a little difficult to make out because for some reason, at least on my system, the column headings in the chart don't show up - but if you highlight the column heading cells you can see what they say.
My Laserjet 2300 worked right out of the box with Windows 7.
Sorry for the long span of time before I replied... really busy. These are a lot of good suggestions and will take a look into each one of them. It will be a little while before I can actually get my hands on her laptop again, hopefully this weekend. I will reply back with my outcome once I have one.
Thank you everyone for replying with great ideas on this, I appreciate them very much.
