.SH ARGUMENTS
.TP
.I display
Specifies a pointer to the Display structure; returned from XOpenDisplay.
.TP
.I output_mode
Specifies how the printer output data is to be handled.
.SH DESCRIPTION
.LP
XpStartJob signals the beginning of a new print job.

If 
.I output_mode 
is XPSpool the X Print Server will automatically spool the 
printer output. If 
.I output_mode 
is XPGetData, then the X Print Server buffers the 
document output for retrieval by XpGetDocumentData. In this case, the print 
server suspends processing further requests on this print context until some 
other client sends XpGetDocumentData. Subsequent operations that use the print 
context may be suspended at any time pending the processing of XpGetDocumentData 
replies to read any buffered output.


XpStartJob sets the job-owner job attribute (included in the XPJobAttr pool) 
immediately prior to issuing the PrintStartJob request. On POSIX systems, the 
job-owner attribute is set using getpwuid_r on the result of getuid. This 
attribute may be used by the X Print Server to identify the user to the spooler.

All changes to the XPJobAttr attribute pool (see XpSetAttributes) must be made 
prior to calling XpStartJob, after which an XPBadSequence will be generated if 
changes are attempted, until XpEndJob is called.

For clients selecting XPPrintMask (see XpSelectInput), the event XPPrintNotify 
will be generated with its detail field set to XPStartJobNotify when the X Print 
Server has completed the PrintStartJob request.

Conceptually, a "Job" is a collection of "Documents", where each Document is in 
turn a collection of "Pages". Depending on the print facilities underlying the X 
Print Server, these delineations may be mapped by a DDX driver into real 
functionality (e.g. see the server attribute multiple-documents-supported).

.SH STRUCTURES
The XPSaveData values for output_mode are defined in <X11/extensions/Print.h>.
:

.nf

    #define XPSpool               1   /\(** Job data sent to spooler */
    #define XPGetData             2   /\(** Job data via XpGetDocumentData */
    
.fi    

.SH DIAGNOSTICS
.TP 15
.SM BadValue
The value specified for output_mode is not valid.
.TP 15
.SM XPBadContext
A valid print context-id has not been set prior to making this call.
.TP 15
.SM XPBadSequence
The function was not called in the proper order with respect to the other X 
Print Service 
Extension calls (example, XpEndDoc prior to XpStartDoc).
