Running Oracle's Virtual Box v4.2.10 r84104 with MSW7ProSP1 32-bit. I have a 5th Generation AirPort Extreme that has a 4-port USB Hub connected to its USB port with external HD and Printer. Successfully added the HD as a Shared Folder and is detected when I access Computer in MSW7ProSP1. On the other hand when I access Devices and Printers/Add a Printer/Add a network, wireless or Bluetooth printer the printer isn't found. It is, on the OS X side, connected/detected via Bonjour no problems there. Any ideas for getting the printer, a Hewlett-Packard LaserJet 1320, detected and usable on inside VB?

Are you in bridged mode on your VM NIC?

You might take a look at this thread: viewtopic.php?f=8&t=9438. This is a few years old, but it worked for me and will probably still work.
