PDF Embed API: Prevent Print and Download

Thank you for viewing this post.
We have disabled the download and print buttons to prevent the users.

{
  showDownloadPDF: false,
  showPrintPDF: false,
}

The problem is when the users `Ctrl+P` or `Cmd+P`,
the following prompt will appear. This gives the user a direct access to download the document.

Before this appear, around a month or so, the "Print" keyboard shortcut calls for the browser print. On which we could somehow prevent the content to be shown.

Any clue could help. 🙂

looks like @Pablo37385995lrkv found a workaround on this issue https://community.adobe.com/t5/acrobat-services-api-discussions/disabled-printing-but-ctrl-p-still-prints/td-p/12019385
I also empty the iframe source in that callback:

adobeDCView.registerCallback(

AdobeDC.View.Enum.CallbackType.EVENT_LISTENER,

function (event) {

if(event.type === "DOCUMENT_PRINT"){

var iframe = document.getElementById("adobe-dc-view").getElementsByTagName("iframe")[0];

iframe.src = "";

location.reload();

}

},

{

enablePDFAnalytics: true,

}

);

Any updates on this issue? I am experiencing the same problem on Firefox and hitting Cmd+P on Chorme brings up the print preview regardless of settings with the PDF showing and the option to save as PDF.

He resuelto el tema hasta ahora protegiendo el archivo con "PDF Services API"

de esta manera al generar el PDF le quito el permiso de imprimir "Protect PDF"

https://developer.adobe.com/document-services/docs/overview/pdf-services-api/howtos/protect-pdf/

y al abrir el PDF desde Adobe Embed muestra el siguiente resultado

de la misma manera adobe deja algunos ejemplos de como hacerlo para este caso con JAVA

Our current workaround is to make the document encrypted and disable printing permission.

Hi Marlo, please could you elaborate more on what you did, I have documented myself and I understand that a password can be added to the PDF with PDF Services API

You could use any PDF library for modifying the file permission. We use a PHP library for implementing this.
If you need more details, a personal message might be more appropriate.
