I’m using 2.19.0 groupdocs viewer. When I try to print jpg/png images I get error that I added as attachment. But I can print pdf.
Also I create a sample project. You can check error with it.
We are sorry to hear that you have such issue. To resolve it please change .UsePdfPrinting(true) to .UsePdfPrinting(false) and you will be able to print the image file.
Thank you it works now.
