Shared printer user rights

Hello,

I have recently installed a printer in a network where users are part of an active directory. The printer is connected through a USB to a client pc and I shared it for the rest of the network to use it. The point is that I messed user rights up and now I am locked out… I can not access the printer settings, delete the printer’s installation or do anything at all.. Can you please help me ?
PS. Not even administrator account helps ..
