Why do i have to keep repairing permissions for my samsung SCX-4500?

Question

Recently (since installing OS X  10.8) when I am sending something to my printer, Samsung SCX-4500 (Darth Vader decor), I will be asked for a certificate and then there will be request to repair permissions for the printer. Once that is done, the printer will print fine. But then some hours or days later I am asked to jump through the same hoops.
Anyone else...?

Please describe exactly what happens and what you do to recover, including the complete, verbatim text of any error messages you see, and any relevant messages from the log:
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Select "/var/log/cups/error_log" from the file list on the left side of the Console window. If you don't see that list, select
View ▹ Show Log List
from the menu bar. Then select the messages from the time of the last failed printing attempt. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
