Hi WhatJac3,
Perhaps you also have an incorrect calling convention defined?

Maybe

Code:
function gl2psEndPage(): GLInt; stdcall; external 'gl2ps.dll';
should be?

Code:
function gl2psEndPage(): GLInt; cdecl; external 'gl2ps.dll';
hmm...if the DLL doesn't export any routines, the code wouldn't compile, would it?

cheers,
Paul
