Selecting Printer Features 74
The %%Session command is supported only for the standard Ethernet and most other
optional network interfaces. It is not supported for jobs submitted through any other
interface—parallel, optional serial, or optional LocalTalk interface. Use of the
%%Session command in print jobs submitted over non-network communication
channels may lead to incorrect or erroneous output. See “Job Boundary Commands”
on page 79 for more information on terminators for serial and parallel protocols.
Session Command Location
The %%Session command must
Be placed at the beginning of the data stream of a document to delimit the session
boundaries.
Precede all of the data that belongs to an individual subjob. This will ensure that the
command is not saved in the actual data stream that is passed to a language or emula-
tion.
Some host applications add DOC commands at the beginning of a document’s data stream
before transmitting a job to the Crown printer. If you do not ensure that such features are
completely disabled, the processing of the %%Session command will be terminated, and
unexpected results may be printed.
Alternatively, if FTP is used to transmit a document to a Crown printer supporting the
%%Session command, the following FTP command must be entered prior to sending a
file to the printer:
cd no_doc_cmds
The default mode of the FTP protocol for the Crown printer adds network addressing
information, in the form of DOC commands, to the start of a job and this data would also
terminate the session.
Session Command
Since each subjob may use a different end-of-subjob argument, the %%Session: ...
command sequence must be inserted at the beginning of each subjob to specify the
end-of-subjob argument for that particular subjob.
Function: Signal the start of a subjob within a session.
Syntax:
%%Session: mode argument terminator
