The Print Preview Components v5.12 has been released. This is a bugfix/maintenance release for Delphi 6 and earlier only.
TPageSetupDialog component is not available in Delphi versions before Delphi 7, and because of that the
SetPageSetupParameters and GetPageSetupParameters methods of TPrintPreview control cannot be available for those versions of Delphi too.
Missing this point was causing the Print Preview components could not be installed on Delphi 6 and earlier.
