Users who run Windows 7 Enterprise x64 in our network have trouble printing to our HP LaserJet M5035 MFP. Items will sit in the queue until the printer itself is power cycled and then items that were already in the queue will print. Any items added later will not print until the printer is power cycled once more. User running our other supporting operating systems (xp professional x86 and vista enterprise x86) do not have this problem. Furthermore, if a X64 win 7 machine is hooked directly to the printer via USB, it works fine.
