In point 2 ports are mapped via telephone connections. Who needs this "exotic" method? It would be helpful at this point instead WIFI and USB port to perform. Links below to find even a prohibition sign for USB is shown. The remaining points to 18 would have been able to save, because the preparations are shown of course anyway. After a device was not trying to set up via USB for the first time, I experienced my negative miracle here. Although the procedure has been complied with, according to CD and the wizard carried out the automatic setup, it was after some time only the message "failed". Also check the term network and network status, with mostly incomprehensible for a device user Therefore, technical terms brought nothing. So I installed the printer for several hours, angry failed attempts, on Windows easily in a few minutes using an existing with me, matching USB cable. It prints and copies since then perfect. If someone has problems with expressions such as TCP / IP Setup, default gateway, etc., I recommend him to set up via USB cable. The purchase price of approximately 5.00 is worth it!
