No point discussing this if neither of us is going to prove it one way or the other.

Bitmaps are actually a key part of what I was thinking about, so you agree with me there it seems. There’s also the issue of using the wrong paper size. .IIRC Windows usually defaults to Letter for printing even in places where A4 is the only common size and no one has heard of Letter, and most people don’t realise their prints are cropped/resized. This would still apply when printing to PDF.
