//! \brief The QsciPrinter class is a sub-class of the Qt QPrinter class that
//! is able to print the text of a Scintilla document.
//!
//! The class can be further sub-classed to alter to layout of the text, adding
//! headers and footers for example.

    //! Format a page, by adding headers and footers for example, before 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 page.  The first page is numbered 1.
