If you follow the instructions my Vorschreibers Roberto and the software including instructions raises directly into the dustbin, the device is actually configured in 20 minutes. I would describe myself as inclined users and not as an expert.
The trick is the reconfiguration of the WLAN card to the PC, assigning a new IP address for the print server in the range of the router used and then resetting the WLAN card to the original settings.
I WISH YOU SUCCESS!
