Agree with all of the above! Last year I got a new PC - and yes it was on Vista. So then I needed new printer drivers and a new driver for scanner & fax.
So I searched by company name (HP, epson ettc), then support or vista drivers, then I was able to find new drivers for my stuff. It's a pain to do, but necessary.
One bit of advice when you get a new Vista computer - I would turn OFF the "automatic update" feature for Vista. When it wants to update something - I'd do web searches on the subject and check to see if the update will do more harm than good... (Like the "update" that so famously ruined my Word 2007)
good luck!
