I know this has been posted on GeoNet in the past but I wanted to revisit this issue again to see if there were any updates from Esri on the topic. Right now we are facing some fairly serious issues printing from the Runtime (using client-side API's in WPF, like ExportImageAsync) as the output is very low quality and does not meet our customer's needs, especially for larger print/plot outputs. Higher quality printing was available in some form in 10.x and I was hoping to get some updates from Esri on when that would be available in the 100.x version of the Runtime. With Esri's focus on cartographic excellence, I'm somewhat surprised by the results we're seeing.
This is causing us some major problems rolling out software to our customers.
This problem has been bothering me for a long time since i use sdk 100.3，but It hasn't been solved from 100.3 to 100.7， use 4k monitor to export (use ExportImageAsync) are only a temporary solution
