Blurry Printing

My pdf file contains text and barcode image.
After print with PdfViewer, texts are OK but barcode is so blurry

See my attachment for example. Please help me!


PdfViewer oViewer = new PdfViewer();

oViewer.AutoResize = false;
oViewer.AutoRotate = false;
oViewer.RenderingOptions.BarcodeOptimization = true;
System.Windows.Forms.PrintDialog printDialog = new System.Windows.Forms.PrintDialog();

if (printDialog.ShowDialog() == DialogResult.OK)
System.Drawing.Printing.PrinterSettings ps = printDialog.PrinterSettings;
printDialog = null;
return Content(“Print Error!”);

if (oViewer.PrintStatus != null)
return Content(“Print Error!”);


Thanks for contacting support.

Please try using oViewer.PrintAsImage = true; property and in case the problem still persists, please share the resource PDF file so that we can further investigate the problem in our environment. We are sorry for this inconvenience.
