PDF in Layout prints in Windows blurred

good morning, I have a PDF file as file in field in a Layout, printing well in MacOS, but in Windows it's just blurred.
What to do?
Thanks
Louis

I’d suggest reading this:

There are other posts about this in the community, such as:

The first post would indicate the version of Windows FileMaker is running on could be a factor. There are work arounds suggested on these posts, but we primarily use Windows servers and clients and haven’t seen these problems. It certainly used to be a known issue on older versions of FileMaker.

thanks, will check and tell
Louis
