I can't find anywhere in the documentation where this is even discussed. To me, this seems like a pretty critical feature for outputting files for print. Am I overlooking this somewhere in the docs? I'd love to output 300 DPI files for my production application. Please help! Thanks.

Besides embedded images, which you control the DPI of, PDFs are all vector and can be scaled to any size. There are 72 points per inch in the PDF model, but that's just so you can accurately set the dimensions of things in the PDF. When it is printed or displayed, the viewer will render the PDF to the right output resolution.

72 DPI isn't accurate, when you need millimeter accuracy (e.g for printing) and got a pretty big file. Is there no way to use a 300 DPI grid instead of 72?

@Leandros Try using decimal fractions of a point. You can use as many decimal places as you like. Actual accuracy depends on output device. If you use an old 9-pin Epson dot matrix printer, you'll still get 72 DPI :)
