I’ve got a 210t as well.
Manuals are nearly non existent. All online now.
I have mine hooked up with roll feed. And USB wire. WiFi… No.
I also have a brother all in one. It does 11×17, legal, and letter. It is very fast. It scans, and does fax. It can scan and make PDF, or jpg.
I’ve never bought ink for it. It is very miserly on ink. I paid slightly less than 300 for it.
So, I’ve got 2 printers. I use 28 lb paper in the brother. It makes very good prints.
I hate HP. They pretend to care, but deliberately make their stuff crazy. I replaced the main board in my t120. It refused to work. It actually has software to block you from getting parts from another machine, to fix it. Very non-consumer friendly.
