Hi,

I'm marking this thread as an approved public feature request so it will be visible in Progress® Kendo UI® for jQuery Feedback Portal so you could track its status and vote for raising its priority for future implementation:

Hi,

Since PDFViewer uses the built in browser dialog you could consider creating a custom print command which attaches a handler to afterprint event which is raised after the user prints, or if they abort the print dialog:

https://dojo.telerik.com/AferICUW/2

https://developer.mozilla.org/en-US/docs/Web/API/Window/afterprint_event 

From the information came upon, however, I couldn't find a way to distinguish the print click from the cancel click.

I hope you will find this information useful.

Hello,

Thank you for contacting us and sharing your feedback about the PDFViewer widget. The following help article demonstrates how you could customize toolbar tools:

https://docs.telerik.com/kendo-ui/controls/PDF/PDFViewer/toolbar#toolbar-and-tools 

https://dojo.telerik.com/ipOTeYOc/3 

You could control the PDFCiewer tools through the toolbar.items collection:

https://docs.telerik.com/kendo-ui/api/javascript/ui/pdfviewer/configuration/toolbar.items

You could find customized Print command on the following dojo:

https://dojo.telerik.com/ipOTeYOc/6

To call the print command you can use the execute method: https://docs.telerik.com/kendo-ui/api/javascript/ui/pdfviewer/methods/execute

You could use the following command for the PDF command:

$("#pdfViewer").data("kendoPDFViewer").execute({command: "PrintCommand"}); 

The Download default document name could be controlled through messages.defaultfilename

https://docs.telerik.com/kendo-ui/api/javascript/ui/pdfviewer/configuration/messages.defaultfilename

https://dojo.telerik.com/ipOTeYOc/7

Regarding your second question, the PDF viewer converts the PDF into an image before sending to the Print dialog, could you give us more details about that requirement so we will do our best to try to find a solution?
