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.
Functions
gtk_printer_new ()
GtkPrinter * gtk_printer_new (const gchar *name
,GtkPrintBackend *backend
,gboolean virtual_
);
Creates a new GtkPrinter.
Since 2.10
gtk_printer_get_backend ()
GtkPrintBackend *
gtk_printer_get_backend (GtkPrinter *printer
);
Returns the backend of the printer.
Since 2.10
gtk_printer_get_name ()
const gchar *
gtk_printer_get_name (GtkPrinter *printer
);
Returns the name of the printer.
Since 2.10
gtk_printer_get_state_message ()
const gchar *
gtk_printer_get_state_message (GtkPrinter *printer
);
Returns the state message describing the current state of the printer.
Since 2.10
gtk_printer_get_description ()
const gchar *
gtk_printer_get_description (GtkPrinter *printer
);
Gets the description of the printer.
Since 2.10
gtk_printer_get_location ()
const gchar *
gtk_printer_get_location (GtkPrinter *printer
);
Returns a description of the location of the printer.
Since 2.10
gtk_printer_get_icon_name ()
const gchar *
gtk_printer_get_icon_name (GtkPrinter *printer
);

gtk_printer_get_job_count ()
gint
gtk_printer_get_job_count (GtkPrinter *printer
);
Gets the number of jobs currently queued on the printer.
Since 2.10
gtk_printer_is_active ()
gboolean
gtk_printer_is_active (GtkPrinter *printer
);
Returns whether the printer is currently active (i.e. accepts new jobs).
Since 2.10
gtk_printer_is_paused ()
gboolean
gtk_printer_is_paused (GtkPrinter *printer
);
Returns whether the printer is currently paused. A paused printer still accepts jobs, but it is not printing them.
Since 2.14
gtk_printer_is_accepting_jobs ()
gboolean
gtk_printer_is_accepting_jobs (GtkPrinter *printer
);
Returns whether the printer is accepting jobs
Since 2.14
gtk_printer_is_virtual ()
gboolean
gtk_printer_is_virtual (GtkPrinter *printer
);
Returns whether the printer is virtual (i.e. does not represent actual printer hardware, but something like a CUPS class).
Since 2.10
gtk_printer_is_default ()
gboolean
gtk_printer_is_default (GtkPrinter *printer
);
Returns whether the printer is the default printer.
Since 2.10

gboolean
gtk_printer_accepts_pdf (GtkPrinter *printer
);
Returns whether the printer accepts input in PDF format.
Since 2.10
gtk_printer_list_papers ()
GList *
gtk_printer_list_papers (GtkPrinter *printer
);
Lists all the paper sizes printer
supports.
This will return and empty list unless the printer’s details are
available, see gtk_printer_has_details()
and gtk_printer_request_details()
.
Returns
a newly allocated list of newly allocated GtkPageSetup s.
[element-type GtkPageSetup][transfer full]
Since 2.12
gtk_printer_compare ()
gint gtk_printer_compare (GtkPrinter *a
,GtkPrinter *b
);
Compares two printers.
Since 2.10
gtk_printer_has_details ()
gboolean
gtk_printer_has_details (GtkPrinter *printer
);
Returns whether the printer details are available.
Since 2.12
gtk_printer_request_details ()
void
gtk_printer_request_details (GtkPrinter *printer
);
Requests the printer details. When the details are available,
the “details-acquired” signal will be emitted on printer
.
Since 2.12
gtk_printer_get_capabilities ()
GtkPrintCapabilities
gtk_printer_get_capabilities (GtkPrinter *printer
);
Returns the printer’s capabilities.
This is useful when you’re using GtkPrintUnixDialog’s manual-capabilities setting and need to know which settings the printer can handle and which you must handle yourself.
This will return 0 unless the printer’s details are available, see
gtk_printer_has_details()
and gtk_printer_request_details()
.
Since 2.12
gtk_printer_get_default_page_size ()
GtkPageSetup *
gtk_printer_get_default_page_size (GtkPrinter *printer
);
Returns default page size of printer
.
Since 2.14
gtk_printer_get_hard_margins ()
gboolean gtk_printer_get_hard_margins (GtkPrinter *printer
,gdouble *top
,gdouble *bottom
,gdouble *left
,gdouble *right
);
Retrieve the hard margins of printer
, i.e. the margins that define
the area at the borders of the paper that the printer cannot print to.
Note: This will not succeed unless the printer’s details are available,
see gtk_printer_has_details()
and gtk_printer_request_details()
.
Parameters
