How does one set up print composer to output a real world map paper map that is scaled properly so that a manual (real world) scale rule that one places on a paper map is scaled properly in a scale that is actually used out in the field, i.e. useful scales, such as 1:10000, 1:25000, 1:50000.
Each time I set print composer to these above-mentioned scales, and then print the map as an output, the scales do not correspond to an old fashioned scale rule, which means the map is not useful out in the field. Is there a way to set print composer properly to output a paper map at the right scale.
