Physically disconnect printers that are directly connected to the Source Server
Before you demote the Source Server, physically disconnect any printers that are directly connected to the Source Server and are shared through the Source Server. Ensure that no Active Directory objects remain for the printers that were directly connected to the Source Server. The printers can then be directly connected to the Destination Server and shared from Windows SBS 2011 Standard.

For now just move the printers around and plan ahead for 64bit drivers and possibly 32bit workarounds.
