Was accustomed quickly delivered from Amazon. Warranty extension to three years without problems and afloat on HP side (was criticized in other reviews). Unpacking, just stand up, remove labels, press Duplex unit back, load paper and connect it to power. Then accompanying startup Installing the cartridges (flap open front and cartridges by lightly pressing fix). Then automatically starts a program which printer in the printer display information about current promotions (alignment printheads, test print, ...). Then wireless connection set up (very simplistic). Other settings I made directly via the web browser. Printer has been detected on Windows 7 Pro 64bit immediately in Windows XP, the driver is required, which is available on the HP side. Finally, install HP ePrint app on smartphones and two furnished. So far, everything works fine. Duplexing I have not tried yet.
Negative: Actually, should a few DINA4 HP paper pages are included. For me, unfortunately, nothing was there. Bearable. 5 Stars.
If my review is helpful I am very pleased with your vote.
