Extensions dompdf - page orientation (v2025)

inability to orient the page with the dompdf landscape extension version 2025.12

Note that the setting only calls dompdf's setPager() in ExportPdf:

$this->dompdf->setPaper($this->PageSize, $this->PageOrientation);

If you meant the exported PDF is not in "landscape", you may check $this->PageOrientation in ExportPdf and the page's ExportPageOrientation property.

If you meant the content does not auto-fit the size in landscape orientation, dompdf cannot do that. You need to adjust the number of fields to export and the font size yourself.
