The driver that was setup by Bonjour on Windows XP for my Photosmart C3180 was for some other HP printer (I forget the model). When this Bonjour configured driver was being used, I
was able to access the printer properties and print a test page. When I changed the printer definition to use the HP Photosmart C3180 driver, I could no longer access properties and could no longer print.
I've uninstalled and re-installed Bonjour for XP and the HP Photosmart drivers with no success.
I tried sharing the printer connected to the Mac-mini using Windows networking and from Windows, I could actually print but garbage came out (looked like PCL codes or maybe PostScript commands).
Peace...
