Asked for password of a user in the _lpadmin group when using a printer


When attempting to add/remove a printer, change printer settings or pause/resume a print queue it may ask you to enter a username and password of the _lpadmin group with the following message:

“Type the name and password of a user in the “_lpadmin” group to allow [printer name] to make changes.”


  1. Logon as an admin user.
  2. Open Terminal (found in Applications -> Utilities)
  3. Now type, or paste in the following line:
    dseditgroup -o edit -p -a admin -t group _lpadminYou will be asked for your password. When putting this in you will not see any asterisks(*) appear.

This will resolve the problem for all admin users. However, if you have standard users which are affected then put this additional line into Terminal:

dseditgroup -o edit -p -a (shortname) -t user _lpadminReplace “(shortname)” with the shortname of the user.
For example: dseditgroup -o edit -p -a carl -t user _lpadmin
