Sharing Printer from Vista x64

I have a desktop running Vista Ultimate x64 that I'm trying to share a
HP Photosmart 7760 to several laptops. One laptop is running Vista Home
Premium 32bit and the other two are running XP 32bit.

When I try to connect any of the laptops to the shared printer it says
the server for the printer does not have the correct driver installed.
It then gives you the option to install the printer driver locally. The
problem is all of these laptops already have the printer installed as
the printer used to be shared off a XP desktop. So if the print driver
is already installed, why are they having an issue connecting to the
printer?

I've tried installing the 32bit drivers on the host machine but it just
ends up reinstalling the 64bit drivers. If I try to add the driver
manually it wants to look for an inf file and I can't seem to find the
correct one.

Any idea's on this? The printer driver package on HP's website is the
same for 32bit and 64bit Vista. If I try to install the XP printer it
just ends up installing the same 64bit driver.

I'm a little frustrated....
