The ZoomChanged event doesn't fire when the user clicks on the zoom in/out buttons or selects a new zoom level from the ComboBox.

If you compare the print quality against the Kendo UI jQuery PDF viewer, the quality difference is night and day. We did not investigate what is happening under the hood in both components. However, the same printing dialog appears when printing via both components and both of them are web components, which indicates to us, that this issue is not related to the browser.

I am opening a standard PDF document and it is not properly displayed in the PDF Viewer. For example, you can see the logo and the table borders but the text of the PDF is missing. If you open the same document in a normal Adobe viewer it is fine.

If the PdfViewer is initialized with a default document, the display performance of this document will be a lot worse, compared to PDF documents that are loaded programmatically after the component is already on the web page.
