I have a 3 MiFi dongle and an HP all-in-one 4500 WiFi printer. I can get the printer to talk to MiFi but I can’t get my laptop to talk to the printer. Is there a way I can print without connecting the printer to the laptop with a cable?
Frankly, I have never tried such a setup but MiFi devices do use standard WiFi technology so if both, your computer and the printer are connected to it they should be able to communicate.
Usually printers with network capabilities have a web interface so I would suggest to lookup the local IP of your printer and put it into the address field of your browser to see if you can reach the web interface.
