The printer I purchased was so difficult to set up I had to hire an IT professional to do it. It took him two hours and cost me more than the printer itself.
Excellent printer, holds a lot of paper and prints smooth. I do miss the auto paper tray on my old 7640. Easy to setup. Scanner also works great. Have been using the HP print plan. Do not have to go looking for ink. It is sent to you before you need it.
The printer is quieter than other models i had and it pronts and copies double sided which i love. The worst thing is the wireless setup and periodic loss of connection.
