My only conclusion is is that some banks use some feature built in PDF Readers to prevent the printing of a PDF, by covering parts with black bars.
The issue does not appear when using other software like Adobe Reader or Microsoft Edge, to print the PDF.
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?
Oh I can understand that, i too cannot accept anything less than total dominion over my devices. Well if this is a firefox specific feature, the only way I could think to access that toggle would be by typing about:config into your search bar and seeing if you can find whichever setting controls this and changing it to false. You know, just be careful though rooting around the guts of your browser.
Chrome acts the same way. Edge and Adobe (on windows at least) ignore this security thing. But if the setting is present in about:config at all, it’d be finding a needle in a haystack. I’m surprised I couldn’t find anything on the internet. If you don’t know the name, it’s impossible to find I guess. To make things even worse, I am able to print the PDF fine on another computer, using the exact same OS, browser, and printer.
