I have a Debian server with cups installed to serve up my HP LaserJet 2100 PCL6 to all machines connected to the network. I can print test pages from cups, but cannot seem to find the correct driver for Win7 x64. I have been to HP site and downloaded their recommended drivers, and choose them (via "Have Disk") when adding the printer but when I print a test page it prints a page saying "protocol not supported". Any idea?
Found it. Have to use the HP LaserJet 2200 Series PCL 5 driver included with win 7. The 2100 series drivers provided by HP did not work for me.
