Summary: mostly, a terrific printer. Three minor issues encountered.I'll get the issues out of the way first. Complaint #1: the WiFi set up was awful. I tried three times to get my password in. I finally got the printer on my home network, after a lot of annoyance. I was not able to get the printer registered into the "HP Smart" software system. I carefully deleted every bit of the "HP Smart" software. Complaint #2: the LED display panel on top of the printer has a small visible flaw, a black line that will not go away. The display is quite small and hard to read already, and this flaw is not helping. Complaint #3: it appears that the toner cartridge has an electronic chip in it. This prevents third parties from selling replacements, you have to buy the HP cartridge. Around $105 at this writing.Otherwise, a fabulous printer. After enduring two defective printers (Brother and Lexmark) I am very pleased. The print quality is terrific. In a week of use, I have not experienced any paper jams. I have printed lots of double-sided and legal size. No issues. The printer if fast. Unlike every other printer I have used, this one has a 5 GHz WiFI radio. In my home, the 5 GHz network is very much faster than the 2.4 GHz network.This is not a cheap printer, so I have to hope that it will last a few years at least. Looking at and squeezing the various plastic parts of the printer, it all seems like average quality consumer electronics to me. Thin, cheap plastic for the most part, but certainly not out of the ordinary. I am cautiously optimistic.
