Thanks! That helps! Doing full page painting will work!
Yes, I'm generating these PDFs for viewing.
Thanks for the other info as well. I'm curious about your comment about
printers with white ink. Presummably they could print on a black piece of
paper. Would Qt support that? Or would the only way to support that be via
the setFullPage option?

I am trying to print a QTextDocument to PDF using QPrinter like the

black background and I can't figure out how. If I do painter.fillRect() it
doesn't cover the margins (margins are white). I've tried changing the
document() stylesheet with no success. Does anyone know what is the best
way to have a different color background for a PDF? Thanks!
You have to set the full page mode of the printer:
http://doc.qt.io/qt-5/qprinter.html#setFullPage
...otherwise it respects margins, which e.g. under Windows means the
margins of the worst printer you've got set up.
I presume you are generating those PDFs for display, not for printing.
Otherwise you need to be aware that anything that has an explicit color
will use toner or ink (yes, there are printers that have white ink). And
if you print it anyways: the margins of your printer are a hardware
property - so they'll be visible no matter what you tell QPrinter.
