Does anyone know trick to solve problem of matrix-codes/QR-codes not being printed
We just had an exam today, but during the exam we found out that the printer did not print the matrix-code/QR-code on each page (although they are present in the original Zesje-generated PDF file). Apparently our printer was not doing a proper job.... Solution that I have tried: scan the exam, copy the matrix-code from exactly the same page of the original PDF and paste it graphically (e.g. using Adobe Acrobat) on the scanned exam page. This has worked in a test. We suspect ~50 of such erroneous pages, so that's still a lot of work. Does anyone know another trick to solve this issue? Regards Eric Verschuur
