I had the same problem but I was able to correct this by a little trial and error. I used a print layout that is exactly 803 pixel wide and I increased the font size to 16. I have a merge field that is 803 pixels wide on the layout. When it prints I get a 8.5 by 11 page which looks like a 12 pt font on the page. This page has about a quarter inch margin all around the page. Hopefully this issue will be addressed in the next release of FM GO.
Thank you for your post.
Currently, FileMaker Go cannot specify a page size. Our Development is aware of this issue.
rgordon - Thank you for your efforts. Hopefully, this will help others as they workaround the issue.

Good to hear about the page size issue and the workaround. Now, if they can get the page break issue resolved, I can restart my project.
