Has anyone else experienced this: I have three Macs at two different locations (one Mac Pro and two Macbook Pros) running Parallels and whenever they print to HP-branded printers the printers produce copy after copy (sometimes over 100). They're all printing over the network and the Mac Pro prints to an HP LaserJet 3550 and the two Macbook Pros print to another model of LaserJet. I've tried every type of driver and configuration, but it still prints multiple copies. It's making things difficult for the clients and the only common denominator is that all three are running Parallels.
Completely shutdown Parallels on all 3 machines and try printing. If the problem still exists then it's a network issue causing the multi-prints. If the problem does not happen after Parallels shutown then I can't ell you why. Are you running it in Coherence. You can try to switch back to OS Window or Full Screen. What Build are you using?
