"Hold for Authentication" When Trying to Print from a Mac
There's already a page about that subject but the thread is close so I tought I would post the solution here.
When you try to print to a Lexmark printer and receive "Hold for Authentication", go see in the printer setting to make sure there's no restriction on Internet Printing Protocol. To do so go in "Settings" then "Security" then "Web Page Password Protect" and scroll down to "Internet Printing Protocol (IPP)" and make sure the setting is "No Security".
