Brochure printing in MAC doesn't scale page

Using Version: Build ID: 8f96e87c890bf8fa77463cd4b640a2312823f3ad on MAC OS Sierra, with Epson WF 2660 printer
Two problems here.

  1. In Print>Paper Handling the suggested paper size is US Legal, although every setting I can find is UK and A4. Why is this?
  2. The brochure prints ok, but the text is reduced in size, i.e. doesn’t fit the page as in the attached picture.
    How do I get a) the suggested paper size to A4, and b) how to get the pages to appear full-size in the brochure?image description

3rd question - why on earth do i need “points” to be able to upload a photograhic aid to demonstrate the problem? Mad.LO Brochure
