In the original DevExp pack we have only dxPSVer.inc for the PrintingSystem.
In the dxPSVer.inc there isn't DEFINE to work with CLX like we have in the cxVer.inc (for grid).
In fact the PrintigSystem only work with VCL.

The version of cxIntlPrintSys3.pas you have, use an {IFDEF VCL} that cause the include of unit QForm 
so when you compile and distibute the EXE you need to distribute qintf70.dll.
This is the BUG.

Diference for cxIntlPrintSys3.pas

OldVersion              NewVersion

{$IFDEF VCL}            Forms,
  Forms,
{$ELSE}
  QForms,                 
{$ENDIF} 


Diference for cxIntlPS3_Editor.pas

OldVersion               NewVersion

  {$IFDEF VCL}
    VCLEditors,          VCLEditors,
  {$ENDIF}


For the new version i have include a new icon for the component.
