Anyone know why I get blank pages when I try to print email from Proton Mail?

I disabled all my extensions and tried reducing the scale in Page Setup. There must be something in Proton Mail that's causing this. There's a "load image" option but that doesn't seem to be the problem.

Forget it. I solved it. You have to go through the print option in Proton Mail at the far right column of the screen under the drop down menu marked "More".
