The map print scale is the scale at which the map will be printed. The map print scale may differ from the "native" scale of the map.  So a map at 1:10,000 can be printed at a print scale of 1:5,000.  Condes automatically magnifies the map to the print scale.

Different canvases can have different map print scales, even when they use the same map.  This allows you to set the same courses on different map scales, even by using the same map for different print scales.

You can change the map print scale at any time.  In order to change the map print scale on a given canvas, please use the setting in the Setup Map dialog, which you find when you use the menu Canvas / Map.

In this dialog, there is a setting called "Print scale".
