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.
