Our printer is telling me that it is successfully setup to my wireless network, yet it won't print. The message I got on my iMac when I try to print is "Looking for printer..." and "Printer Offline." I tried using a USB cable and a Mac Book, and it STILL gives me the "Looking for printer" message. When it does print (which I can't get it do right now), it prints extremely slowly. What could we be doing wrong? Thanks!
