2.2.3 Printer Ticket Interface

The Printer Ticket Interface is identified by the default interface ID 0x00000000. The default interface does not require Query Interface Request (QI_REQ) or Query Interface Response (QI_RSP) messages to initialize the interface. All requests flow from server to client and all responses flow from client to server.

Certain fields in this interface are payload between the client printer driver and the printing subsystem. The content and meaning of these fields depends on internal structures for these two systems and is not interpreted in any way by this protocol. Special consideration has to be taken regarding the implementation on both sides when they are based on different operating systems. The implementation has to translate these operating system-specific differences between the client printer driver and the printing subsystem.
