USB Switches?
RukhWunder asks: "I have two computers and one USB printer. Is there a USB splitter or something around so I can connect them both to the printer? Networking the computers is out of the question because they are on the university network already." There was an earlier question about USB on KVM switches that was done last year, however I too would be curious to note if there are switches for just USB devices.
search for 'usb switch' and the first link that comes up... usbgear.net. $26.50 fer four ports. pretty cool.

It's a K[v]M, but it'll work with printers.
