// The class described here is intended to allow FOX applications to
// print - under Windows it uses the native Windows API while on other
// operating systems and if used to print to file it generates Postscript.

// The basic protocol for use is

//   FXPrintDialog dlg(this, "");
//   dlg.execute();                   // user gets to select a printer
//   FXPrinter printer;
//   dlg.getPrinter(printer);         // find out which one!
//   FXDCNativePrinter ptr(getApp()); // printing framework
//   if (!prt.beginPrint(printer)) FAIL   // unable to print just now
//   FXFont *f1 = prt.fntGenerateFont("courier", 12); // or whatever!
//                                    // font sizes given in points (1/72in)
//   f1->create();                    // remember to make font really there!

//       prt.drawText(x, y, "string", strlen("string"));
