Check your operating system, you should be on either Windows 10 or Windows 11
If you have already installed EDNA, what error message are you getting when you click on Printers > EDNA Printers?
1. Not Connected to EDNA
The print service has stopped for some reason, reboot your computer or EDNA is not running or is frozen and hasn't restarted itself.
Open task manager and right click to restart the EDNA service. You may have to click more details on the bottom lefthand corner of the window to see the services tab. You can also just restart the computer (this will restart EDNA of course).
(Running) - is what you want to see in the Task Manager, Services window.
2. No Supported Printers Found
The print service is running but doesn't see your printers. Power cycle your printers (leaving them off for 10 seconds or so then turning them back on), see if they pop up as being recognized where you add the Add Printer button. Changing USB port(s) that they are plugged into may also make the printer appear if it's not.
