I can't answer this question because I connected the printer via WLAN (Devolo) and USB. But it is very reliable and uses little ink.

I can't judge, because I operate the printer via USB.
But: The printer prints and prints and prints. I am a frequent printer. There is almost no ink consumption. After 6500 A4 printouts I once bought a set of colour for about 30 CHF. I still have 1/4 of that in each bottle and the tanks are still 1/3 full.
This is the best purchase I have made in the past.

Yes, this is the printer, I connected it to our Fritz Box 7630 via WLAN.works perfectly.the biggest advantage is the tank and no more cartridge.print what the stuff holds.
