Graphics, PowerPoint, etc. look good, not pictures.
The detail resolution is not particularly good, and gradations of color blur. eg a mountain range in the bluish haze that reveals at a normal, non-calibrated monitor approximately 7 color gradations, has yet informal term 3. On some papers are the prints clearly too dark. This may be in the nature of things with 600 * 600dpi, you should know before buying though.
The installation was easy. Enter WLAN key Add in WIN 7 a new network printer. Done.
Once I had the printer recently reboot as Windows labeled him as "off line".
