Hello everyone: I have already install the Parallels software and the Windows Xp in my IMac. I works fine so far, but I have a problem. When I try to use the printer, Windows doesn't recognice it, and when I try to install it, iMac OS tell me that there is another aplication is using the USB hardware I'm trying to use, that I have to wait 5 to 10 seconds... and so on. What can I do to install my printer in the Virtual Machine, working with Windows XP My printer is a HP Photosmart 4100. Thanks for your help.
