Installation went incredibly easy. Either via the included installer or simply via the web interface, which proves to be the significantly faster for advanced users.
The steps are very simple: connect the print server via a LAN cable to access a PC, set up WLAN, LAN cable disconnect and connect the printer. Done. The interior of the printer settings is also via installer or "manually" (Printer Properties -> Add port -> Standard TCP / IP port -> Enter the IP Print Server -> ready)
Since I was very pleased, I ordered a second to tie a second printer. Class product!
