+ \class QPrinter
+ \reentrant
+
+ \brief The QPrinter class is a paint device that paints on a printer.
+
+ \ingroup multimedia
+ \mainclass
+
+ 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.
+
+ 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 setNumCopies() 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::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.
