I have 2 all-in-one units connected via network, to 3 computers running Built 7057 64bit.. Samsung CLX-3175 - The 64bit printer drivers install well. The Scanner drivers and utility won't install. HP3310 - Same story. The Scanner utility won't install. I can access the scanners via their IP address and scan on line... but I cannot access the either computer from the scanners themselves. any ideas?
