I for about 9 months use the Brother HL-5170DN is now already in a small network and am very satisfied with the device. Already the first impression of the box and insert the installation CD was overwhelming. Intuitively, the installation of the required files was carried out and after a few steps, I was able to perform the first prints. Even as Netzwerklaie I had no problems to configure the other computers for printing. On the installation CD Maintenance Tutorial is included as a Flash file. If you have problems you will be introduced step by step to the solution. I am glad that I chose for this printer and would buy it immediately.
