Been there and done that. Here's what comes up when you actually click the Vista OS link:
HP LaserJet and Color LaserJet Products - Products Not Supported in Microsoft Windows Vista
Sorry, your product is not supported in the Microsoft Windows Vista Operating System.
For more information of upgrade programs and new product information, please go to the HP Trade-In/Trade-Up Website, or HP Shopping.
We are sorry to inform you there will not be any Windows Vista operating system printer drivers available for your product.
If you are using the new Windows Vista operating system on your PC, consider an upgrade to a newer HP product that will work with Microsoft’s new Vista operating system.
To help you choose a new product upgrade, the following tool will be helpful: http://www.hp.com/support/hho/productreplacement

Needless to say not an acceptable solution. Been doing a lot of reading and think that the series II drivers might work, and then again maybe not. I'll post as soon as I try them.
