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

GtkPrintJob

typedef struct _GtkPrintJob 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

                                                         GtkPrintSettings *settings,
                                                         GtkPageSetup *page_setup);

Since 2.10

gtk_print_job_set_source_file ()

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
error : return location for errors
Returns : FALSE if an error occurred

Since 2.10

gtk_print_job_get_surface ()

cairo_surface_t*    gtk_print_job_get_surface           (GtkPrintJob *job,
                                                         GError **error);

Gets a cairo surface onto which the pages of the print job should be rendered.

job : a GtkPrintJob
error : return location for errors, or NULL
Returns : the cairo surface of job

Since 2.10

gtk_print_job_send ()

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

Sends the print job off to the printer.

job : a GtkPrintJob
callback : function to call when the job completes or an error occurs
user_data : user data that gets passed to callback

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
