We recently tried printing using an area style with the GeoLinearGradientBrush as the Advanced property. We found that the gradient does not draw correctly when creating a pdf with PdfSharp or Microsoft PDF Printer. I have attached a sample project so you can see. Also attached is a sample pdf to demonstrate the problem.
Please have a look and see if it’s a bug.
