ControlPrintProcessor

BOOL  WinprintControlPrintProcessor(
    HANDLE  hPrintProcessor,
    DWORD   Command,
    DWORD   JobId,
    LPTSTR  pDatatype,
    LPTSTR  pSpoolFile
);

Provides control over printing the current document.

Returns TRUE if the operation is successful.

hPrintProcessor	A handle to an open instance of a print processor to control.
Command	Commands used in the spooler's default local print processor are:
	JOB_CONTROL_PAUSE	Pauses the print job.
	JOB_CONTROL_RESUME	Resumes the print job at the point in the spool file where it was paused.
	JOB_CONTROL_CANCEL	Cancels the print job.
JobId	Identifies the job associated with the spool file (not used by the default print processor).
pDatatype	Points to a memory location that contains the spool file datatype (PRINTPROCESSOR_TYPE_RAW or PRINTPROCESSOR_TYPE_EMF for the default print processor).
pSpoolFile	Points to the name of the spool file.

Calls to ControlPrintProcessor can occur asynchronously; the function should not wait for the result. For example, the function could set a flag and return immediately.
