Printer issues after installing Mojave
Since installing Mojave I cannot print. I have na Epson ET 3750. When I select print I get the spinning ball - I uninstalled and reinstalled to printer. I cannot even access printer in system settings - when i select it I get the spinning ball again.
Another possibility is old kernel extensions that haven’t been automatically removed by upgrade procedures. I don’t think they’re as common now but print/scan drivers used to like to add their own tweaks into the extensions library.
Check for any that mention Epson and remove them. If they are actually needed the installation process will reinstall appropriate versions.
