Have the printer now, since January private (about 400 pages) and for the club (certificate printing) in use and can only report good. About USB I've made with the printer to set up the wireless. About the router I run the printer wirelessly network. Reception and speed of printing, print results and the ability to print on both sides are all properly. Without problems to let envelopes (eg DIN long (DL)) print. For envelopes or thicker paper / cardboard (certificates) have to just be aware to use the bypass tray and open the rear exit, so that the material to be printed is not diverted and verknickt over the rollers. But it also indicates a printer or the software. I am with what you would expect from a mono laser printer, completely satisfied.
