Ok this means you don’t have any custom styles. Please, could you try two more things:
Could you download the latest test image you have posted here on the forums and recheck if you can reproduce the issue with it (this is just to make sure that the image didn’t get changed by the upload)
After you are sure the issue still exists, could you add this file style.css (69 Bytes) to your user data folder (the folder shown in your latest screenshot) and try again (restart Tropy before printing)?
Just to make sure we aren’t missing anything, do you create the PDF using this option in the print dialog?
