XpSetImageResolution(3Xp)					 XPRINT FUNCTIONS					 XpSetImageResolution(3Xp)

NAME

       XpSetImageResolution - Sets the resolution for subsequent PutImage requests

SYNOPSIS

	     cc [ flag... ] file... -lXp [ library... ]
	     #include <X11/extensions/Print.h>

       Bool XpSetImageResolution ( display, print_context, image_res, prev_res_return )
	     Display * display ;
	     XPContext	print_context ;
	     int  image_res ;
	     int * prev_res_return ;

ARGUMENTS

       - display
	      Specifies a pointer to the Display structure.

       - print_context
	      Specifies the print context on which to set the resolution.

       - image_res
	      Specifies the image resolution in pixels per inch.

       - prev_res_return
	      Returns the previous image resolution in pixels per inch.

DESCRIPTION

       XpSetImageResolution returns True if the printer server allowed the resolution to be set, otherwise False is returned.

       XpSetImageResolution sets the resolution for subsequent PutImage requests to the screen of the specified print context. If the return value
       is False, then the print server does not support image scaling for the  particular  resolution  given  the  current  configuration  of  the
       printer,  and  the  application	is  responsible  for any desired scaling. If the return value is True, then the contents of any subsequent
       PutImage request to a Pixmap or to a Window on the screen of the specified print context will automatically be scaled as part of the PutIm-
       age request. The scale factor is:

	   default_printer_resolution / image_res

       Where  default_printer_resolution is the current value of that page attribute. Only the image itself is scaled (meaning the effective width
       and height of the image change), the dst-x and dst-y parameters to PutImage are not altered.

       As a special case, a value of zero for image_res resets the resolution to automatically track the printer resolution; in this  case  (which
       is also the default setting for a newly created print context), subsequent images will not be scaled.

       If  the	return value is True and prev_res_return is a non-NULL pointer, then the previous image resolution that was set for the print con-
       text is stored in prev_res_return.

       XpSetImageResolution returns False immediately if image_res is negative or greater than 65535.

DIAGNOSTICS

       XpBadContext   A valid print context-id has not been set prior to making this call.

XpStartJob(3Xp) 						 XPRINT FUNCTIONS						   XpStartJob(3Xp)

NAME

       XpStartJob -  Indicates the beginning of a single print job.

SYNOPSIS

	     cc [ flag... ] file... -lXp [ library... ]
	     #include <X11/extensions/Print.h>

       void XpStartJob ( display, output_mode )
	     Display *display;
	     XPSaveData output_mode;

ARGUMENTS

       display
	      Specifies a pointer to the Display structure; returned from XOpenDisplay.

       output_mode
	      Specifies how the printer output data is to be handled.

DESCRIPTION

       XpStartJob signals the beginning of a new print job.

       If  output_mode	is  XPSpool  the X Print Server will automatically spool the printer output. If 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 XPStartJobNo-
       tify 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 facil-
       ities  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).

STRUCTURES

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

	   #define XPSpool		 1   /* Job data sent to spooler */
	   #define XPGetData		 2   /* Job data via XpGetDocumentData */

DIAGNOSTICS

       BadValue       The value specified for output_mode is not valid.

       XPBadContext   A valid print context-id has not been set prior to making this call.

       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).
