Change the default print settings on a Mac
You must be logged in with an account that has administrator rights on your Mac to change these settings. If you are prompted for a username/password, use the ones for your administrator account on your Mac, not your MIT Kerberos Principle.
This can be done through the cups interface.
- In a browser, go to the webpage 127.0.0.1:631/printers.
Note: If you get an error message such as "cannot connect" or "web interface is disabled", start the Terminal app (in Applications > Utilities) and enter the command: cupsctl WebInterface=Yes
- Select your printer (link is in blue).
- Under Administration, select Set default options.
- Modify the options that you wish to change. In this generic example I have used the generic driver instead of HP, Dell or other so few options are available.
- Click on "Set Default Options" at the bottom of the list of options.
- Enter your administration username and password into the dialog box that appears and then click the blue Okay button in the bottom right corner of the box.
- Go back to terminal and run the command: cupsctl WebInterface=No if you wish for that webpage to be disabled, e.g. public machine.
