Gweilo, thanks for trying to help, but you're not helping. My problem has nothing to do with the things you suggest. Please don't hang around in threads guessing, making people confused. Stick to things you have genuine knowledge about.

Thanks Macropod (And earlier Charles Kenyon) for making it clear what this is about. To me as a consumer it's a bit strange that the printer's non-changeable settings is allowed to alter (the conditions for) my layout - that there is no basic standard all machines must adhere to. But that's really off topic. I've got my answer and I just have to accept this.
