I've updated my print servers and management clients so that I can get the Security tab on the Print Management screen.  I was able to easily create a group that had 'Manage Documents' rights on the print servers.  The existing printers did not pick up that new security setting, but new printers do.

I am looking for a way to do a mass update of all the print queues so they get the new permissions.

Servers: 2008 Enterprise 32 bit (Not R2)
Management Clients: Vista/Win7 32 and 64 bit.

Use setprinter from Server 2003 Windows resource kit.

I know this is an old thread, but I'm having a hard time finding a way to modify existing permissions for all printers on a 2012r2 print server.  The above solution using setprinter.exe would overwrite existing print permissions, this is not effective as I have several hundred print queues with varying permissions - I simply need to 'add' to the existing printer ACL (need to add print operators having the manage printers permission) without removing the already defined permissions.

Is this possible?

We take old threads here too.  I did respond to the new thread you started and thanks for being a PaperCut customer.  Here is the same response if others find this.

In Windows 8 and Server 2012, the print team added many PowerShell commands. The ones you will need to use are get-printer and set-printer but the methodology is a complete replacement.   I cover this process on the Scripting Guy blog.

On a side note, the "Print Operators" group does not have all the permissions in the local security token as a group you add to the machine. If all the tasks are remote, then use Print Operators.

 This is the output from the get-printer call without Print Operators

This is the SDDL after adding Print Operators on 2012R2.
