Thanks It is a PDF417 barcode that is readable by the scanner as an imageview but unreadable when sent to a canvas for printing a pdf.

moore_it Well-Known Member Licensed User Longtime User Jan 30, 2025 #3 It's not possible because the image is a barcode. I think change the objc commands Thanks anyway Upvote 0
