Blurred text on PDFViewer printing with scale less than 200%

Bug report

Currently the result of PDFViewer printing is affected by PDFViewer scale option. When scale is less than 200%, the letters in the printed PDF appear blurred.

Reproduction of the problem

  1. Go to
  2. Set scale option to 100%
  3. Print to PDF using "Microsoft Print to PDF" printer. (The final result is the same compared to actual printing to a physical printer)
  4. For consistency set the following print options, e.g. in Chrome:
  • Paper size: A4
  • Pages per sheet: 1
  • Margins: None
  • Scale: Default

Current behavior

Text in printed PDF file is blurred

400% to 100%

Expected/desired behavior

Text in printed PDF file is clear.
NOTE: Clear text may be achieved if PDFViewer scale option is set to 400% on the demo before printing.

Hello Niketa,

The issue has been fixed with Kendo UI R1 2020 SP1 release. Here you will find a link to the release history. Could you please try to upgrade to a version later than 2020 R1 (I would recommend upgrading to the latest R2 2021 SP1) and check the behavior.

I hope this helps.
