Okay I've read this 5 times and keep getting more confused (it's me not you
). Anyway, are you asking if you can jack your PC in or jack the Printer in to a wireless access point that has a switch on it?
If your printer has an ethernet jack, then just plug that into your switch on your wireless router/bridge and YES you can print wirelessly to that wire(d) printer from your PC.
