Seriously flawed software.
I now find that many others are having the same networking issues. The only work around until recently was to unplug the machine and wait for it to re-attach to the network - ironically you get a little nasty message on the printer that scolds you for unplugging the device.
When it is working (rarely) it works as advertised - nothing outstanding
Constantly loses network connectivity on all four of our family computers and I've spent HOURS AND HOURS installing, reinstalling software and troubleshooting this defective machine; In addtion, it is an outrageously expensive ink cost per page
