I personally don't care if the default printer gets overridden. The users can print where I set them up to print. If they don't like it, they'll call and I can put their workstations in the appropriate default printer group and additional printer groups and they'll be happy. Default printers don't change much unless a new printer is added. The majority of my computers are shared by 20+ nurses or therapists. They print to the closest printer. If they need color, it is an additional printer and they know how to change it. New computers added to the network are put into the same printer groups as the rest of the surrounding computers. Computers that are not shared, do not usually get printers assigned via kixtart and printer groups.
