Printing A3 publisher document with Adobe Acrobat

I made a custom A3 poster in publisher so that I can save it as a PDF and print it off using Adobe Acrobat so it splits across four A4 pages. However, when I come to print in there is a lot of white space around the edge of the poster, as you can see in the picture.

I tried adjusting the zoom in my printer settings but it ended up leaving the white space and just zooming in on the content so half of it was missed out.

Anyone know how to adjust it so it prints to the edge of the page?

Thanks
