Checked with Belkin tech support and it appears that my printer is apparently not one of those in the compatibility list. Darn. I'll have to go back to the store tomorrow to return the wireless print server.
I guess I should have checked compatibility beforehand. And I would, had I known that the list was so specific and had my printer was anything other than a bog-standard USB printer. (It's a HP Laserjet 1000.) As it is, the compatibility list is short enough that perhaps Belkin should have it printed on the product packaging itself.
The other disappointment was that the Quizno's in Hillsdale no longer provides free soda refills. However, the manager only put up the handwritten notice after I had gotten the refill, so I didn't have to pay anything extra. Nevertheless, I'm not going there again.
