Printing

This feature is experimental in version 0.15.

Limitations:

• the protocol and implementation may still change. See ticket #598.
• by default the feature is disabled and you must enable printing in the global configuration file or on the command line
• forwarding is only supported from MS Windows and Posix clients, and only when connecting to a Posix server. (support for MS Windows as server may be added in the future)
• you may hit permission issues (the user running the xpra server must be a printer administrator)
• you may hit issues with selinux (see #598 / #815)
• you are responsible for installing the required dependencies (the packages we provide do not include them)
