Have I bought this unit because my old printer slowly came into the years. Since we have 3 laptops and everyone wants to print it, I signed up for a WLAN variant chosen. Can only say it has everything super in connection device worked. No problems !!! But one must strictly adhere to the installation instructions, otherwise you get Real problems. So, only installation perform then when prompted Establish USB connection. So it works guarantees immediately. For those who do not like instructions, there is a sticker with exclamation sign stuck to the USB socket. Well if it then does not ring? However, the print quality is as usual super at HP. Again, I am extremely satisfied. For scanner I can not write anything yet, but I will raise him soon test times. Copying is ruckzuck from the stage, with very good Quality and fast speed. And even if some on the noises Omit cal, mechanics happens to have its acoustics, and does not bother. The price is currently somewhat higher than before 5Wochen, have also waited a long time, and then strike at the right moment. Otherwise I can for the appliance distribute another 5 stars. Thoroughly recommended !!!
