2.1 Transport

The Remote Desktop Protocol: XPS Print Virtual Channel Extension is designed to operate over dynamic virtual channels, as specified in [MS-RDPEDYC] section 1.3.3.1, using the names TSVCTKT (used to transport Printer Ticket Interface messages) and XPSRD (used to transport Printer Driver Interface messages). If [MS-RDPEDYC] supports version 2 as it is described in section 1.7, then both channels (TSVCTKT and XPSRD) are created with a priority class of 0; otherwise, the channels have no priority assigned to them.
