I am using Larry Stout's PrintPlus widget together with my own printing service and templates to print maps in my application. My basemap and printing templates are in Web Mercator (wkid 3857), the PrintParameters are also set to match the map's spatial reference. However, the scalebars on my printed maps are inaccurate.
I'm aware that Web Mercator isn't the best projection for measuring distances etc, but is there a solution/workaround for this problem? Any help is appreciated.
