The invoice or estimate on screen is now drawn in the printed page's proportions. Text wraps on the same words and every page starts with the same line, so what you arrange is what your customer receives.
Before, the page was the right width but its text was larger, so a long description could run onto more lines on screen than in the file. The page is now a little wider and its text a little smaller. More of a long document fits on screen as a result.
