William Rogers 940306295c Added interface to allow the printer device to be manually opened and closed.
This allows the printer object to retain the host side image cache and helps
the developer to open the printer only as needed to help avoid issues if the
device has been disconnected.

NOTE: This style of usage is optional and standard usage is otherwise unaffected.
