-- A GtkPrintContext 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 t'GI.Pango.Objects.Layout.Layout' and t'GI.Pango.Objects.Context.Context' objects that match the font metrics
-- of the cairo surface.
-- 
-- GtkPrintContext objects gets passed to the [beginPrint]("GI.Gtk.Objects.PrintOperation#signal:beginPrint"),
-- [endPrint]("GI.Gtk.Objects.PrintOperation#signal:endPrint"), [requestPageSetup]("GI.Gtk.Objects.PrintOperation#signal:requestPageSetup") and
-- [drawPage]("GI.Gtk.Objects.PrintOperation#signal:drawPage") signals on the t'GI.Gtk.Objects.PrintOperation.PrintOperation'.
