SetJob function

The SetJob function pauses, resumes, cancels, or restarts a print job on a specified printer. You can also use the SetJob function to set print job parameters, such as the print job priority and the document name.

You can use the SetJob function to give a command to a print job, or to set print job parameters, or to do both in the same call. The value of the Command parameter does not affect how the function uses the Level and pJob parameters. Also, you can use SetJob with JOB_INFO_3 to link together a set of print jobs. See Remarks for more information.

Syntax


BOOL SetJob(
  _In_  HANDLE hPrinter,
  _In_  DWORD JobId,
  _In_  DWORD Level,
  _In_  LPBYTE pJob,
  _In_  DWORD Command
);

Parameters

hPrinter [in]

A handle to the printer object of interest. Use the OpenPrinter, OpenPrinter2, or AddPrinter function to retrieve a printer handle.

JobId [in]

Identifier that specifies the print job. You obtain a print job identifier by calling the AddJob function or the StartDoc function.

If the Level parameter is set to 3, the JobId parameter must match the JobId member of the JOB_INFO_3 structure pointed to by pJob

Level [in]

The type of job information structure pointed to by the pJob parameter.

All versions of Windows: You can set the Level parameter to 0, 1, or 2. When you set Level to 0, pJob should be NULL. Use these values when you are not setting any print job parameters.

You can also set the Level parameter to 3.

Starting with Windows Vista: You can also set the Level parameter to 4.

pJob [in]

A pointer to a structure that sets the print job parameters.

All versions of Windows: pJob can point to a JOB_INFO_1 or JOB_INFO_2 structure.

pJob can also point to a JOB_INFO_3 structure. You must have JOB_ACCESS_ADMINISTER access permission for the jobs specified by the JobId and NextJobId members of the JOB_INFO_3 structure.

Starting with Windows Vista: pJob can also point to a JOB_INFO_4 structure.

If the Level parameter is 0, pJob should be NULL.

Command [in]

The print job operation to perform. This parameter can be one of the following values.

ValueMeaning
JOB_CONTROL_CANCEL

Do not use. To delete a print job, use JOB_CONTROL_DELETE.

JOB_CONTROL_PAUSE

Pause the print job.

JOB_CONTROL_RESTART

Restart the print job. A job can only be restarted if it was printing.

JOB_CONTROL_RESUME

Resume a paused print job.

JOB_CONTROL_DELETE

Delete the print job.

JOB_CONTROL_SENT_TO_PRINTER

Used by port monitors to end the print job.

JOB_CONTROL_LAST_PAGE_EJECTED

Used by language monitors to end the print job.

JOB_CONTROL_RETAIN

Windows Vista and later: Keep the job in the queue after it prints.

JOB_CONTROL_RELEASE

Windows Vista and later: Release the print job.

 

You can use the same call to the SetJob function to set print job parameters and to give a command to a print job. Thus, Command does not need to be 0 if you are setting print job parameters, although it can be.

Return value

If the function succeeds, the return value is a nonzero value.

If the function fails, the return value is zero.

Remarks

Note  This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation—factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.

You can use the SetJob function to set various print job parameters by supplying a pointer to a JOB_INFO_1, JOB_INFO_2, JOB_INFO_3, or JOB_INFO_4 structure that contains the necessary data.

To remove or delete all of the print jobs for a particular printer, call the SetPrinter function with its Command parameter set to PRINTER_CONTROL_PURGE.

The following members of a JOB_INFO_1, JOB_INFO_2, or JOB_INFO_4 structure are ignored on a call to SetJob: JobId, pPrinterName, pMachineName, pUserName, pDrivername, Size, Submitted, Time, and TotalPages.

You must have PRINTER_ACCESS_ADMINISTER access permission for a printer in order to change a print job's position in the print queue.

If you do not want to set a print job's position in the print queue, you should set the Position member of the JOB_INFO_1, JOB_INFO_2, or JOB_INFO_4 structure to JOB_POSITION_UNSPECIFIED.

Use the SetJob function with the JOB_INFO_3 structure to link together a set of print jobs (also known as a chain). This is useful in situations where a single document consists of several parts that you want to render separately. To print jobs A, B, C, and D in order, call SetJob with JOB_INFO_4 to link A to B, B to C, and C to D.

If you link print jobs, note the following:

  • Jobs can be added to the beginning or end of a chain.
  • All jobs in the chain must have the same data type.
  • The chain must be completely linked before spooling begins, otherwise the spooler may print and delete spooled jobs before you link them all. There are two ways to keep the chain from printing prematurely:
    • Pause the first job in the chain until the chain is completely linked. The paused state of the first job governs the state of all jobs in the chain.
    • Keep the first job incomplete, that is, do not call EndDoc or ScheduleJob for the first job. However, if 'print while spooling' is enabled (the default), this method blocks the port while the chain is built, which also prevents the printing of non-related jobs.
  • The application must handle the case where the user deletes a job in the chain before the chain finishes printing. GetLastError returns INVALID_PARAMETER when a JobID does not exist.
