Hi which barcode do you mean?If you print the entire email, the ANNEXE form won't fit on one page in the PDF format.
The best solution is select the entire contents of ANNEXE table (Chrome will print/save only the selected contents) in the PPR email >> right click >> select Print option in google chrome >> Change print option to Save PDF.
Now, the entire ANNEXE form including the barcode will come on single PDF page. Trust me it works.
If you have any questions, let me know.
I have printed ANNEX A easily in one page, it's like a table
