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 https://demos.telerik.com/kendo-ui/pdfviewer/index
  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.

Tools' tooptips are localized and can be modified via messages. However, the tools in the overflow menu (when window size is resized) have the original tool text.
