I'm using ArcGIS Server 10.2.2, to get prints for my webmap (json) by using PrintingTools (GPServer). The layers and basemap prints fine but legend for points and polygons features get distorted on A0 size template. I tried the same webmap with A4 and A3 template which works great. Here is the image of Distorted Legend after A0 print.
But if I take Export Map on same A0 template from ArcGIS Desktop(10.2.2) it works fine. Below is the image of Legend.
Is it a limitation of ArcGIS? How should I get the features legend on A0 size by using Export Web Map Task??
