Description

A GtkPrinter object represents a printer. You only need to deal directly with printers if you use the non-portable GtkPrintUnixDialog API.

A GtkPrinter allows to get status information about the printer, such as its description, its location, the number of queued jobs, etc. Most importantly, a GtkPrinter object can be used to create a GtkPrintJob object, which lets you print to the printer.

Printing support was added in GTK+ 2.10.
