New issue 313: Layout pieces too close to right edge https://bitbucket.org/valentinateam/valentina/issue/313/layout-pieces-too-close-to-right-edge
Susan Spencer:
When printing layouts to desktop printer or to large format plotter, the rightmost lines are cut off by the printer. (Rightmost edge of layout as viewed in Layout mode)
Increase the border on the right side of layouts by a very small amount (two or three line widths?), this should fix the problem.
