The EZXS55W IS a 10/100 switch, so It's unclear what you're asking. I'll assume, for the sake of trying to come up with an answer, that you want to know if you can plug the printer directly in to the switch, or print through a computer that has the printer attached.
If that is correct, you'd only be able to plug the printer directly in to the switch if it is network capable. In other words, it would have an ethernet module installed that has an RJ45 jack, and would be TCP/IP configurable.
If that isn't what you're asking, then please clarify.
