This section describes the implementation of the Raw Socket protocol in the varioPRINT 140 Series. This mechanism allows the varioPRINT 140 Series to communicate with the host system in order to print files. The Socket interface (sometimes called a TCP stream interface) provides a low-level, reliable network interface to the host system or host application. Network communication with the host is based on TCP/IP protocols. The physical connection between host and varioPRINT 140 Series is based on an Ethernet TCP/IP connection. There is no high-level network protocol on top of the TCP protocol. All data received during one single connection are treated as one single job. A job is considered complete when the socket connection is closed by the host. Multiple jobs must be separated by closing and then opening the connection again. Only one connection is accepted at a time for all modes. You cannot configure this.
You can use the Socket connection in Document Printing mode.
Job attributes are not transmitted from the client with Socket printing. If there is a Job ticket, job attributes are extracted from it. However, if job attributes are not present in the ticket, default values are defined for job publishing. These are:
Username: Socket
User Hostname: Socket
Host Jobname: SocketJob
A default queue can be provided for socket connections. Default attributes for this queue can be defined in an automated workflow.
