I want to create a PDF-file which people can download from my website and then print out on their own printer. The PDF-file will be a simple A4 page (UK/Europe) with mainly text and some graphics.
Ideally I would like to 'frame' the A4 page with a 10mm grey border, but most people will not be able to print this page as most printers cannot print right to the edge.
Question: How many mm do I have to stay away from the edges so that 'most' people can download and print this A4 page properly? Is there some kind of 'rule' or 'industry standard' that I can follow?
Is there anything else I should keep in mind before I make this PDF-file available online?
