Group Pol to Allow Install Local Printer

When tech support staff want to add printers for users from Add Printer Wiz, option to add local printer is grayed. I thot I could fix this with a group policy for the computers OU that gave support staff the right to load device drivers, BUT the option to add local printer is still grayed out. Is there a simple way to delegate this responsibility without adding a new admin account to every machine in my school district?
