Recently I needed to do an odd bit of printing. I needed to generate an A3 PDF for printing which had crop marks around it. That means it needs to be printed to "a bit larger than A3" size. In the past I'd used Foxit's PDF printer for this (where it just worked), but that no longer seems to be free. Turns out the default Windows PDF printer needs a bit of hackery to enable using odd-sized paper. I'm sure I'll find myself needing to do this again in the future, so this is a reminder for my future self.
