When troubleshooting printing issues on a Mac, one of the first steps is to enable CUPS. CUPS is a network printing service used by Mac computers. It allows you to set up your printers on a network, and customize options such as cash drawer setup.
How to Enable CUPS
To get started, go to https://localhost:631/printers/. This should bring up a screen with a heading that says "Web Interface is Disabled."
You should see the message 'The web interface is currently disabled. Run "cupsctl WebInterface=yes" to enable it.'
Select and copy the text
Next, click the magnifying glass icon in the top right-hand corner of your screen and search for "Terminal".
Once in the Terminal, paste in the text
cupsctl WebInterface=yes and press the RETURN key.
You should now be able to go to https://localhost:631/printers/ and sign in to see your installed printers.
Your username and password for CUPS will be the same as your Mac username and password. You can check your Mac username in System Preferences > Users & Groups.
To change settings for your printer, click the printer name.
