Hello! I take my Macbook Pro to two different locations. One location has an HP wireless printer, and the other an Epson. Both are setup on Mac OS X Lion and work fine. Windows 7, on the other hand, while running as a VM constantly installs the newly found printer that's not there. Just about any action on the Mac side will prompt Windows to try to install the printer. I'm guessing it's a problem with Parallel's tools. Just an FYI.
