Hosting shared printers on Vista?

On my little home network, I have a couple of old printers, an HP LaserJet 5L and a Lexmark X73. They do most of what I need.

I recently got a new machine that came with Vista which I want to put in the location where these two printers live. Right now the vista box can use these two printers just fine hosted on a Win XP box which is directly connected to them, but I don’t think I can find Vista drivers for either one. Can I install an XP driver on the Vista box and share it, or should I go looking for a new printer?
