Using usb printer for home group.

I perchased a WRN3500L router to be able to use a usb printer from any computer in my house with out having to have one computer on as printer host. I am unable to do this even with following the steps provided in the Genie. I run in to this modle is not supported for print server funtion. Not a Worning it's just not on any of the lists. I know that most of the new printers these days are wifi but I can not afford them yet. Any aid in this endever would be greatly apprecieated.
