//! headers and footers for example.

//! the document text is drawn on it. \a painter is the painter to be
//! used to add customised text and graphics. \a drawing is TRUE if
//! the page is actually being drawn rather than being sized.
//! \a painter drawing methods must only be called when \a drawing is
//! TRUE. \a area is the area of the page that will be used to draw
//! the text. This should be modified if it is necessary to reserve
//! space for any customised text or graphics. By default the area is
//! relative to the printable area of the page. Use
//! QPrinter::setFullPage() because calling printRange() if you want to
//! try and print over the whole page. \a pagenr is the number of the
