## Detailed Description

A Printer object represents a printer.

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

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

Since gtkmm 2.10:

## Constructor & Destructor Documentation

## Member Function Documentation

bool Gtk::Printer::accepts_pdf | ( | ) | const

Returns whether the printer accepts input in PDF format.

Since gtkmm 2.10:

Returns:
  `true` if printer accepts PDF.

bool Gtk::Printer::accepts_ps | ( | ) | const

Returns whether the printer accepts input in PostScript format.

Since gtkmm 2.12:

Returns:
  The printer's capabilities.

Glib::RefPtr<PageSetup> Gtk::Printer::get_default_page_size | ( | ) | const
