They make 802.11b print servers…not cheap ~$125+, but it will make the printer wireless so you can print from anywhere you get 802.11b signals near your hub.
Another option is a external IR device to hook up to the TR.
Finally, if you have other computers, just hook the HP to one, share the printer, then use the TR to either wirelessly or ethernet connect to your network and print.
Personally, I have 2 printers and use a bit of both. My HP has a dedicated print server, wired, and my Minolta is connected to a Celeron 333 MHz which acts as a print sever (it was lying around and I didn’t want to spend another $150).
