Next thing appear is a pop up which guide you through an automatic installation where download (you had to be connected to internet) and install and set the printer (kind of "next > next > next ...").

Use
After the guided installation ended the printer is ready to work: both printer and scanner (M1120 is scanner/printer/photocopier).

Problems
The integrated scanner work with xsane, but here the problem in the title (the "but..."): the area you select in the preview is "uncalibrated"; so it may difficult scan just single area of the pages. Everything else work fine (both scanner and printer feature).
