I think some banks utilize some feature built in PDF Readers to PREVENT printing of “SENSITIVE” information in a PDF, by blocking parts with black bars.

The issue does not appear when printing using other software like Adobe Reader or Microsoft Edge, to print the PDF. (So all on Windows.) So it’s not a driver issue.

Is this a form of DRM? I want to know how it works whatever is causing it, and be able to REMOVE it from the PDF itself completely.

Why does Firefox obey this “DRM” crap, while Edge has the balls to ignore it?

And to make things even more complicated, I am able to print the PDF fine on another computer, using the exact same OS, browser, and printer. So it appears to be a specific setting or version of .e.g Firefox?

If only I had NAME for this, then I’d be able to search for it online.
