I have a 2012r2 print server that I migrated all my 2008r2 print queues to. The permissions for all printers migrated successfully, and I now need to make a change to them all. I just need to add the print operators group and give them the manage documents permission. This seems like it should be a simple task, however so far all I can find is how to modify the default permissions for all NEW printers (done) and how to change (and replace) all permissions for all print queues (using setprinter.exe utility). If there was a way to use the setprinter.exe utility to add to existing permission lists rather than replacing them, that would be sufficient, but it is my understanding that this method will replace all my existing permissions, this is not acceptable as they are different for each printer.
Is there a way to do this other than manually one-by-one?
