also gives you the flexibility to override the major document’s global
printing attributes for one or more subjobs.
printing attributes for one or more subjobs.
Some printer description languages support language-specific
markers which work well when the complete document is composed
of a single printer description language generated by a single
application. However, language-specific markers do not work very
well when you need to create a document from files using multiple
printer description languages. In such cases, high-level document
manipulation applications find it difficult to deal with markers without
taking into account the language and semantics of the
language-specific delimiters.

Sessions solve that difficulty by offering a language-independent
means of combining multiple subjobs.

How is a Session Used?
A session is invoked by the DOC %%Session command.
Language-independent delimiters included in the command allow any
data acceptable to an emulation, including 8-bit data, to be trans-
ferred to the printer without terminating documents or subjobs early
and out of context.

Note: The session mechanism is supported only for optional network
interfaces on QMS Crown printers at this time. It is not supported for jobs
submitted through any other interface LocalTalk, parallel, or serial. Use of
the %%Session command in print jobs submitted over non-network
communication channels may lead to incorrect or erroneous output.
