Hi. My elementary os 5.1 sees all the network printers but they are all disabled. strange thing is that I can print on them , then after some minutes of inactivity they stop working. I opened all the firewall ports (cups hplip avahi ) but stll no difference. I wonder where i can find a tutorial for connecting to network printers that is good to elementaryos Last question. what is the function of the big button on the right to the name of the printer in printer settings? if i switch it on nothin happens...
