Your 4880 just needs to be linked into the existing network. This could be done in many ways. You might like to look at Ethernet over Power solutions, which have really come of age (5 years ago they sucked). In most situations, if you have power you can get a network connection, and obviously you do have power.
To do it wirelessly (not as good as Ethernet over Power these days, in my opinion, but still viable) would mean putting a wireless router next to your printer, plugging the printer into it, and then using that router to link to your existing wireless network. Depending on the hardware you have/obtain will depend as to how you achieve this.
Truly, though, if you want simplicity look at EoP.
