## Description

A GtkPrintJob object represents a job that is sent to a printer. You only need to deal directly with print jobs if you use the non-portable GtkPrintUnixDialog API.

Use `gtk_print_job_get_surface()` to obtain the cairo surface onto which the pages must be drawn. Use `gtk_print_job_send()` to send the finished job to the printer. If you don't use cairo GtkPrintJob also supports printing of manually generated postscript, via `gtk_print_job_set_source_file()`.

Printing support was added in GTK+ 2.10.

## Details

### struct GtkPrintJob

    struct GtkPrintJob;

The GtkPrintJob struct contains only private members and should not be directly accessed.

### GtkPrintJobCompleteFunc ()

    void                (*GtkPrintJobCompleteFunc)          (GtkPrintJob *print_job,
                                                             gpointer user_data,
                                                             GError *error);

The type of callback that is passed to `gtk_print_job_send()`. It is called when the print job has been completely sent.

`print_job` : | the GtkPrintJob
`user_data` : | user data that has been passed to `gtk_print_job_send()`
`error` : | a GError that contains error information if the sending of the print job failed, otherwise `NULL`

### gtk_print_job_new ()

    GtkPrintJob *       gtk_print_job_new                   (const gchar *title,
                                                             GtkPrinter *printer,

    gboolean            gtk_print_job_set_source_file       (GtkPrintJob *job,
                                                             const gchar *filename,
                                                             GError **error);

Make the GtkPrintJob send an existing document to the printing system. The file can be in any format understood by the platforms printing system (typically PostScript, but on many platforms PDF may work too). See `gtk_printer_accepts_pdf()` and `gtk_printer_accepts_ps()`.

`job` : | a GtkPrintJob
`filename` : | the file to be printed

    void                gtk_print_job_send                  (GtkPrintJob *job,
                                                             GtkPrintJobCompleteFunc callback,
                                                             gpointer user_data,
                                                             GDestroyNotify dnotify);

### gtk_print_job_set_track_print_status ()

    void                gtk_print_job_set_track_print_status
                                                            (GtkPrintJob *job,
                                                             gboolean track_status);

If track_status is `TRUE`, the print job will try to continue report on the status of the print job in the printer queues and printer. This can allow your application to show things like "out of paper" issues, and when the print job actually reaches the printer.

This function is often implemented using some form of polling, so it should not be enabled unless needed.

`job` : | a GtkPrintJob
`track_status` : | `TRUE` to track status after printing

Since 2.10

### gtk_print_job_get_track_print_status ()

    gboolean            gtk_print_job_get_track_print_status
                                                            (GtkPrintJob *job);

Returns wheter jobs will be tracked after printing. For details, see `gtk_print_job_set_track_print_status()`.

`job` : | a GtkPrintJob
Returns : | `TRUE` if print job status will be reported after printing
