Hi, I have files saved in /file-asset/ which I need in window.print() but somehow the print opens up and blocks the images. I wanted to know the reason for this. Is it from browser side or salesforce side? Do we have solution to resolve this issue or it will go as known limitation.

Yes, it is definitely possible to include these images in the print. Since enabling 'Background Graphics' didn't resolve it, the issue is how the browser handles Salesforce's secure URLs during printing.
I suggest we implement one of the following fixes---->
Base64 Encoding (Best Solution)--> We convert the image into a data string directly in the code. This embeds the image into the page so the browser doesn't have to 'fetch' it, ensuring it appears every time.
Static Resources---> Moving the images to Static Resources makes them more accessible to the browser's print engine compared to /file-asset.
