/**
* @brief Provides an OS-independent interface to printing.
*
It allows to use all FLTK drawing, color, text, and clip functions, and to have them operate
on printed page(s). There are two main, non exclusive, ways to use it.
<ul><li>Print any widget (standard, custom, Fl_Window, Fl_Gl_Window) as it appears
on screen, with optional translation and scaling. This is done by calling print_widget()
or print_window_part().
<li>Use a series of FLTK graphics commands (e.g., font, text, lines, colors, clip) to
compose a page appropriately shaped for printing.
</ul>
In both cases, begin by start_job(), start_page(), printable_rect() and origin() calls
and finish by end_page() and end_job() calls.
<p><b>Platform specifics</b>
<ul>
<li>Xlib-based platforms (<i>e.g.</i>, Linux, Unix): this class is implemented as
a subclass of Fl_PSfile_Device.
Use the static public attributes of this class to set the print dialog to other languages
than English. For example, the "Printer:" dialog item Fl_Printer::dialog_printer can be set to French with:
\code
Fl_Printer::dialog_printer = "Imprimante:";
Fl_Printer myprinter;
myprinter.start_job();
\endcode
Use Fl_PSfile_Device::file_chooser_title to customize the title of the file chooser dialog that opens
when using the "Print To File" option of the print dialog.
Class Fl_RGB_Image prints but loses its transparency if it has one.
<li>MSWindows platform: Transparent Fl_RGB_Image 's don't print with exact transparency on most printers.
Fl_RGB_Image 's don't rotate() well.
A workaround is to use the print_window_part() call.
<li>Mac OS X platform: all graphics requests print as on display.
</ul>
\brief Print support under MSWindows and Mac OS X.
*
Use Fl_Printer instead that is cross-platform and has the same API.
Fl_Printer is typedef'ed to Fl_System_Printer under MSWindows and Mac OS X.
