Hi Guys,

do you have any idea about how to print PDF from File Column in Dataverse? It can be downloaded but before download, we want to print PDF directly from Canvas app Edit form or Model driven app main form.

thank you

Hannah

Print PDF from File Column in Dataverse

@Daivat Vartak (v-9davar)

Again thank you very much for your expertise.

Unfortunately, there is not URL for the PDF stored in File column in Dataverse. That's the hurdle of this print function.

The file column has download function coming out of box. But the end user prefer to print before downloading as they download with the final purpose of printing and then deleting the downloaded copy. So if they can print directly from model driven app, that'll be much better.

There is an experimental control 'PDF viewer' which resolved the view/display PDF content feature. 'PDF viewer' is used in that canvas app embedded in main form of Model Driven app. But according to the limitations of 'PDF viewer', it doesn't support printing currently. therefore, when I tried print() power fx function in that canvas app, it doesn't work, just showing a blank of sheet paper.

So, the options 2 and 3 are good to explore but I am not that confident though. Option 4, I was trying to find any PCF from PCF gallery but no right solution there.

Anyway, a big thanks to you.

Print PDF from File Column in Dataverse

Hello HH-22102055-0,

You're looking to print a PDF directly from a File column in Dataverse, either within a Canvas app or a Model-driven app, without requiring the user to download it first. This is a common requirement, but it's not a straightforward process due to browser security restrictions. Browsers generally prevent websites (including your apps) from directly printing content from arbitrary URLs without user interaction (like clicking a download button).

Here's a breakdown of the challenges and possible approaches:

Challenges:

Browser Security: As mentioned, browsers restrict direct printing from URLs without explicit user action. This is a security measure to prevent websites from silently printing unwanted content.

PDF Rendering: The PDF needs to be rendered in a way that the browser's print functionality can access it.

Possible Approaches (with Caveats):

IFrame Approach (Canvas Apps and Model-driven Forms - Simpler, but limitations):

How it works: You can embed an iframe in your app and set the src attribute of the iframe to the URL of the PDF file in Dataverse. Then, you can use JavaScript to trigger the iframe's print functionality.

Caveats:

Cross-Origin Restrictions: If your Canvas app or Model-driven app and your Dataverse instance are on different domains, you might run into cross-origin resource sharing (CORS) issues. You'll need to configure CORS on your Dataverse instance to allow your app's domain to access the PDF files.

User Interaction: Even with an iframe, you might still need some user interaction (like clicking a button) to initiate the printing due to browser security. Silent, automatic printing is usually blocked.

Styling: Controlling the styling of the printed PDF can be challenging with iframes.

PDF.js or Similar Library (Canvas Apps - More Control):

How it works: You can use a JavaScript library like PDF.js (provided by Mozilla) to render the PDF directly within your Canvas app. This gives you more control over the PDF display and printing.

Caveats:

Complexity: Integrating a PDF rendering library requires more development effort.

Performance: Rendering large PDFs can be resource-intensive, especially on mobile devices.

Server-Side PDF Generation (Most Robust, but complex):

How it works: You could create a custom API (e.g., using Azure Functions or Power Automate) that fetches the PDF from Dataverse, generates a print-friendly version (if needed), and then returns it to your app. This bypasses some of the browser restrictions.

Caveats:

Complexity: This is the most complex approach, requiring server-side development.

Cost: Using Azure Functions or other serverless services might have associated costs.

Third-Party PDF Viewers/Printers (Explore):

Check AppSource: Explore the Dynamics 365 Marketplace (AppSource) for any third-party PDF viewer or printing solutions that might offer direct printing from Dataverse.

Hi,

There is a new feature available in PowerApps called PDF function but it is existing in the experimental mode. Please check the below link to know how to enable it in your canvas app.
