If the problem is a shortage of ports, and you have to unplug the printer to plug something else in, then it's doubly important that you follow a proper disconnect procedure. The same procedure applies to things like cameras, etc. Improper disconnect and plugin has been suggested as one of the causes for "loss of format" in camera memory chips, which can cause loss of pictures and/or other hassles.

If you just don't have enough ports to leave things plugged in, as Sorcha suggests a 4-port USB hub, a little larger than an audio tape cassette, shouldn't cost you more than about $20. Plug-and-Play with any Windows system should take care of all the setup for one.
