Having had to prepare many documents - fortunately in english language only - that would format properly and print out legibly in almost every country on earth (see weird Japanese paper sizes, for example, and note that the US rarely uses A4), I have reverted to creating documents in Libreoffice and exporting as PDF. This seems to perfectly in the great majority of cases. Else use Latex or a Pagemaker clone. You will hear quick enough if it comes out junk at the receivng end. Jump on a plane and take a paper copy with you if it is that important - and your boss will wear the cost....
