I have had so many problems with this piece of garbage. After much effort, I finally got the printer working with the 3 computers in my home (2 PC, 1 Mac). I had to change the password on my network, so I updated all the machines, including the printer. Now the Mac works, but I have not been able to get the Windows machines to recognize the printer. A couple months later, my Mac can't find the printer either! Nothing has changed on my network in these last couple months. And I don't have time to spend another 6 hours trying to debug this thing again.It appears that HP has seriously lost their mojo in printers, which used to be their strong suit. This printer is the biggest piece of junk since the last HP printer I returned.Never again, HP. Thanks for nothing...
