I have 2 HP8600 printers on the same network, one is mine and one is my wifes.
I can print from my IMac to the 8600 which is connected to the network via ethernet (mine), i can set up and see the other printer but when i send a print job to it the print job gets queued and the printer status goes to busy, but it never prints.
I can print from my windows 7 laptop (HP).
I have removed and reinstalled the printer several times. I have even wired the computer directly to the wifi network extender. This is a netgear 2500 network ext (WN2500RP)
I have also updated the bios on the printer
