  APrinterIndex: Integer;
begin
  APrinterIndex := dxPrintDevice.FindPrintDevice('Microsoft XPS Document Writer', '');
  if APrinterIndex <> -1 then  // If the specified printer device is available
    dxPrintDevice.PrinterIndex := APrinterIndex;  // Changes the active printer device

#include "dxPrnDev.hpp"  // This header declares the dxPrintDevice function

// ...
  int APrinterIndex = dxPrintDevice()->FindPrintDevice("Microsoft XPS Document Writer", "");
  if (APrinterIndex != -1)  // If the specified printer device is available
    dxPrintDevice()->PrinterIndex = APrinterIndex;  // Changes the active printer device
