Code Example

The following code example sets Microsoft XPS Document Writer as the active printer device for TdxComponentPrinter:

Delphi

uses
  dxPrnDev;  // This unit declares the dxPrintDevice function

// ...
var
  I: Integer;
begin
  for I := 0 to dxPrintDevice.PrinterCount - 1 do
  begin
    if dxPrintDevice.Printers.Strings[I] = 'Microsoft XPS Document Writer' then
    begin
      dxPrintDevice.PrinterIndex := I;  // Changes the active printer device
      break;
    end;
  end;
end;

C++

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

// ...

  for (int i = 0; i < dxPrintDevice()->PrinterCount; i++)
  {
    if (dxPrintDevice()->Printers->Strings[i] == "Microsoft XPS Document Writer")
    {
      dxPrintDevice()->PrinterIndex = i;  // Changes the active printer device
      break;
    }
  }
