PDF Embed API: Prevent Print and Download

[Marlo:ASI]

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. 🙂

Also, we tried accessing the iframe document, to override "keydown" listener, but the CSP policy prevents us.

I was able to confirm this on Firefox and I reported it internally. 

[Marlo:ASI]

Thank you!

Hopefully can solve this issue asap.

[Marlo:ASI]

Good day Raymond, may we know if there is any progess? 🙂
I could confirm that it is still showing the "download" button up to now.
Thanks

[Raymond Camden]

It was confirmed by engineering. That's all I got for now.

Quedo al pendiente tambien del tema para resolve este inconveniente, nosotros lo detectamos en Chrome y Edge (Ctrl + p)

[Marlo:ASI]

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

[Marlo:ASI]

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.

Hi Marlo,

I have just DM'd you about this as we are running into a similar problem. I can't seem to see the message in my dashboard so please let me know if you've received the message, and if not could you please DM me with a quick insight into how you did this with PHP?

Thank you

Evan

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.

[Raymond Camden]

Sorry no.

[carlos adalid5E27]

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

Hi @Raymond Camden , IIRC, this was working fine some time ago. Can you confirm if this was introduced in a recent release. Also, I could not find a way to use a prev. version of the SDK. Do you support it in any way ?

[Raymond Camden]

Unfortunately we do not provide a way to use previous versions of the library. It is a known request.

Hi @Raymond Camden, do you have an idea if this issue has been resolved?

[Raymond Camden]

Nope, I've got no insight into that I'm afraid. 

[adebayo227118878dfp]

Okay, thanks.
Can you suggest any Laravel/PHP package for PDF protection to prevent the Ctrl + P issue?

looks like @Pablo37385995lrkv found a workaround on this issue https://community.adobe.com/t5/acrobat-services-api-discussions/disabled-printing-but-ctrl-p-still-p... 
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,

}

);
