Question

Disabled Printing but CTRL + P still prints

Hello -

So I've disabled printing and downloading in the embed API per the documentation (showPrintPDF and showDownloadPDF are set to false). I've also set a css attribute to @media print { display: none} for the container div. Both of these methods work and cover the file -> print (PDF does not display in file -> print which is good). However, when a user mouses over the document and hit CTRL (CMD) + P, they are still able to print. How can this be disabled? I've tried the @media print route with no luck. 

Screenshot attached of the print dialog that comes up with CTRL + P.

      I solved this by Capturing PDF Embed API Events, when a user try to print it returns a "DOCUMENT_PRINT" type event, so there u can handle it.
      Keep in mind that this is a callback, so the printing cannot be stopped by setting an event.preventdefault, my solution has been to reload the page so the printing is cancelled, it is not the cleanest solution but it is the only one that I have found.
      Heres a code example:

              adobeDCView.registerCallback(
              AdobeDC.View.Enum.CallbackType.EVENT_LISTENER,
              function (event) {
                  if(event.type === "DOCUMENT_PRINT"){
                      location.reload();
                  }
              },
              {
                  enablePDFAnalytics: true,
              }
          );

        Hello,

        Sorry to hear that you are facing this issue. Which embed mode do you use to display the PDF?

        When showPrintPDF is false, Embed API will not print the PDF file through its own print code, however, the browser will still print the contents of the body tag. With the embed mode set to "IN_LINE", it will appear that the PDF is printing when in fact it isn't. To prevent the printing of the contents of the element that Embed API draws into, add a CSS statement to hide the element that you are using for the divId. Be sure to add !important because... well... it's important.

         

        Note: I've only tested this in Chrome. Let me know if you are seeing other behavior in other browsers and please be specific as to version numbers.

         

         

        <!doctype html>
<html>
<head>
	<meta charset="UTF-8">
	<title>Shouldn't Print</title>
	<style>
		body {
			padding: 0;
			margin: 0;
		}

		@media print {
			.noprint {
				display: none !important;
			}
		}
	</style>
	</style>
</head>
<body>
	<div id="adobe-dc-view" class="noprint"></div>
	<script src="https://documentcloud.adobe.com/view-sdk/main.js"></script>
	<script type="text/javascript">
		document.addEventListener("adobe_dc_view_sdk.ready", function () {
			var adobeDCView = new AdobeDC.View({ clientId: "cdd2f1b0e6e84f7a8eb71e7ac84530fa", divId: "adobe-dc-view" });
			adobeDCView.previewFile({
				content: { location: { url: "bodea-summary.pdf" } },
				metaData: { fileName: "Bodea Summary.pdf" }
			}, { showPrintPDF: false, embedMode: "IN_LINE" });
		});
	</script>
</body>
</html>

        Hi, thanks for the detailed answer - followed this but still having the issue. I'm able to select Save as PDF in the print dialog and I'm still able to successfully save it and print it using this method. But, specifically through CTRL + P - this method works on File -> Print.
