  \class QPrinter
  \reentrant

  \brief The QPrinter class is a paint device that paints on a printer.

  \ingroup printing


  This device represents a series of pages of printed output, and is
  used in almost exactly the same way as other paint devices such as
  QWidget and QPixmap.
  A set of additional functions are provided to manage device-specific
  features, such as orientation and resolution, and to step through
  the pages in a document as it is generated.

  When printing directly to a printer on Windows or Mac OS X, QPrinter uses
  the built-in printer drivers. On X11, QPrinter uses the
  \l{Common Unix Printing System (CUPS)} or the standard Unix \l lpr utility
  to send PostScript or PDF output to the printer. As an alternative,
  the printProgram() function can be used to specify the command or utility
  to use instead of the system default.

  Note that setting parameters like paper size and resolution on an
  invalid printer is undefined. You can use QPrinter::isValid() to
  verify this before changing any parameters.

  QPrinter supports a number of parameters, most of which can be
  changed by the end user through a \l{QPrintDialog}{print dialog}. In
  general, QPrinter passes these functions onto the underlying QPrintEngine.

  The most important parameters are:
  \list
  \i setOrientation() tells QPrinter which page orientation to use.
  \i setPaperSize() tells QPrinter what paper size to expect from the
  printer.
  \i setResolution() tells QPrinter what resolution you wish the
  printer to provide, in dots per inch (DPI).
  \i setFullPage() tells QPrinter whether you want to deal with the
  full page or just with the part the printer can draw on.
  \i setCopyCount() tells QPrinter how many copies of the document
  it should print.
  \endlist

  Many of these functions can only be called before the actual printing
  begins (i.e., before QPainter::begin() is called). This usually makes
  sense because, for example, it's not possible to change the number of
  copies when you are halfway through printing. There are also some
  settings that the user sets (through the printer dialog) and that
  applications are expected to obey. See QAbstractPrintDialog's
  documentation for more details.

  When QPainter::begin() is called, the QPrinter it operates on is prepared for
  a new page, enabling the QPainter to be used immediately to paint the first
  page in a document. Once the first page has been painted, newPage() can be
  called to request a new blank page to paint on, or QPainter::end() can be
  called to finish printing. The second page and all following pages are
  prepared using a call to newPage() before they are painted.

  The first page in a document does not need to be preceded by a call to
  newPage(). You only need to calling newPage() after QPainter::begin() if you
  need to insert a blank page at the beginning of a printed document.
  Similarly, calling newPage() after the last page in a document is painted will
  result in a trailing blank page appended to the end of the printed document.

  If you want to abort the print job, abort() will try its best to
  stop printing. It may cancel the entire job or just part of it.

  Since QPrinter can print to any QPrintEngine subclass, it is possible to
  extend printing support to cover new types of printing subsystem by
  subclassing QPrintEngine and reimplementing its interface.

    \enum QPrinter::PrinterState

    \value Idle
    \value Active
    \value Aborted
    \value Error
*/

/*!
    \enum QPrinter::PrinterMode

    This enum describes the mode the printer should work in. It
    basically presets a certain resolution and working mode.

    \value ScreenResolution Sets the resolution of the print device to
    the screen resolution. This has the big advantage that the results
    obtained when painting on the printer will match more or less
    exactly the visible output on the screen. It is the easiest to
    use, as font metrics on the screen and on the printer are the
    same. This is the default value. ScreenResolution will produce a
    lower quality output than HighResolution and should only be used
    for drafts.

    \value PrinterResolution This value is deprecated. Is is
    equivalent to ScreenResolution on Unix and HighResolution on
    Windows and Mac. Due do the difference between ScreenResolution
    and HighResolution, use of this value may lead to non-portable
    printer code.

    \value HighResolution On Windows, sets the printer resolution to that
    defined for the printer in use. For PostScript printing, sets the
    resolution of the PostScript driver to 1200 dpi.

    \note When rendering text on a QPrinter device, it is important
    to realize that the size of text, when specified in points, is
    independent of the resolution specified for the device itself.
    Therefore, it may be useful to specify the font size in pixels
    when combining text with graphics to ensure that their relative
    sizes are what you expect.

  available to the application.
