So I just had to purchase a new printer, wound up with the HP Officejet Pro 8610. Had no problem hooking it up to my iMac, used the USB Cable. Now I am trying to add it to my other computers on my network and my MBP won't find it. I have even typed in the direct IP address and still no luck. Any clues what is going on or what I can do to get it to work? On the iMac, I have it set to share that printer on the network.
