@Generated("org.javagi.JavaGI")
public class PrintJob
extends GObject

Represents a job that is sent to a printer.

You only need to deal directly with print jobs if you use the non-portable PrintUnixDialog API.

Use getSurface() to obtain the cairo surface onto which the pages must be drawn. Use send(PrintJobCompleteFunc) to send the finished job to the printer. If you don’t use cairo GtkPrintJob also supports printing of manually generated PostScript, via setSourceFile(String).

setSourceFd

public boolean setSourceFd(int fd)
                    throws GErrorException

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 Printer.acceptsPdf() and Printer.acceptsPs().

This is similar to setSourceFile(String), but takes expects an open file descriptor for the file, instead of a filename.

Parameters:

fd - a file descriptor

Returns:

false if an error occurred

Throws:

GErrorException - see GError

setSourceFile

public boolean setSourceFile(String filename)
                      throws GErrorException

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 Printer.acceptsPdf() and Printer.acceptsPs().

Parameters:

filename - the file to be printed

Returns:

false if an error occurred

Throws:

GErrorException - see GError

setTrackPrintStatus

public void setTrackPrintStatus(boolean trackStatus)

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.

Parameters:

trackStatus - true to track status after printing

onStatusChanged

public SignalConnection<PrintJob.StatusChangedCallback> onStatusChanged(PrintJob.StatusChangedCallback handler)

Emitted when the status of a job changes.

The signal handler can use getStatus() to obtain the new status.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• PrintJob.StatusChangedCallback.run()

emitStatusChanged

public void emitStatusChanged()

Emits the "status-changed" signal. See onStatusChanged(PrintJob.StatusChangedCallback).

builder

public static PrintJob.Builder<? extends PrintJob.Builder> builder()

A PrintJob.Builder object constructs a PrintJob with the specified properties. Use the various set...() methods to set properties, and finish construction with PrintJob.Builder.build().

Returns:

the builder object
