# Gtk::PrintContext Class Reference
[Printing]

Inheritance diagram for Gtk::PrintContext:

[legend]
List of all members.

## Detailed Description

A PrintContext encapsulates context information that is required when drawing pages for printing, such as the cairo context and important parameters like page size and resolution.

It also lets you easily create Pango::Layout and Pango::Context objects that match the font metrics of the cairo surface.

PrintContext objects gets passed to the begin-print, end-print, request-page-setup and draw-page signals on the PrintOperation.

Since gtkmm 2.10:

Glib::RefPtr<Gtk::PrintContext> wrap | ( | GtkPrintContext * | object,
|  | bool | take_copy = `false` |
| ) |  |  | `[related]`

Parameters:

  | object | The C instance

Parameters:

  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:
  A C++ instance that wraps this C instance.
