Altatac via Walmart offers the refurbished HP Photosmart 5520 Wireless All-in-One Color Inkjet Printer, which also scans and copies, for $51.95 with free shipping. That's the lowest price we could find for a refurb by $5, and $90 under what you would pay for a new unit. It features 1200x600 dpi black resolution, 4800x1200 dpi color resolution, 2.65" touchscreen, 802.11n wireless, and USB connectivity.

A 1-year warranty applies, although it's unclear who backs it.
