I'm running Snow Leopard Server as guest OS under Parallels 7 build 7.0.15054 (host OS is Lion). I've correctly specified my USB printer (EPSON Sytlus Photo 2200) in the hardware configuration. But when I try to add the printer in the Print and Fax Preferences, the only printer shown is HP Color Laserjet 8500. I do not have any HP printer. The System Profiler also shows only the supposed HP printer, and the Epson printer utility program also does not find the printer. What am I doing wrong?
