for each OS?
I've got a Canon MX700 printer that is plugged into my router. I've reserved the ip number 192.168.0.100 via the router's web interface using the printer's MAC address. So I can now ping the printer from all computers on the LAN and I can get to the printer's web interface from all machines. However, try as I might, none of the computers can add the printer. I've tried from a new Windows10 machine, a Macbook pro and a Ubuntu 18.04 computer. They all time out and claim they can't contact the printer. Any suggestions much appreciated.
