Has anyone encountered printing issues w/ CS5? We are unable to print more than one copy at a time (in either Win7 64-bit or 32-bit). This issue pertains to our HP DesignJet 500 plotters; EPSON WorkForce 1100 and HP Color LaserJet 2600n printers. I have found a tweak for the HP LaserJet 5100's, but nothing for the aforementioned equipment.
