Printing out flight plan maps

[RayM]

Using Plan-G3 (v3.0.1.50) on Windows 7 64-bit.

When I print out the flight plan maps I can only get them to print out to images that are 21x14cm on my A4 sheets. It makes no difference whether I set my printer to Portrait or Landscape.
Is there a way to get them to print out to cover an A4 sheet?

Otherwise I think I am getting the hang of this very interesting bit of kit. Thanks.
