Bad print quality

[Harald]

I have a dynamically generated document in a RadRichTextBox. When I print this document, the quality (graphics) is very bad.

1.PrintSettings printSettings = new PrintSettings();
2.printSettings.DocumentName = _protocol.Title + " - Protokoll";
3.printSettings.PrintScaling = PrintScaling.ShrinkToPageSize;
4.printSettings.PrintMode = PrintMode.Native;
5.this.documentViewer.Print(printSettings);

If I export the document as pdf and print the PDF document, then the print quality is fine.

How can I improve the print quality of the RadRichTextBox?

Hi Harald,

May I ask you to check if the resolution of the images is higher than their size? If that is true then you hit an already logged issue. The bug is caused by an optimization, which decodes the images with the size currently visible in the viewport, and not the original size. You can track its progress, subscribe for notifications about status changes and add your comments to it on the following link - RichTextBox: Images are visualized and printed with low quality. I am afraid that we have not been able to find a workaround for this case by now.

Please, let me know in case you think that case on your end might be a different one.
