File Name Issue in Edge Browser's Print Dialog Feature (index.pdf)

Question

In the Edge browser, I am opening the file specified in the src of an iframe as shown below. However, when trying to save it as a PDF, the file name appears correctly in the Chrome browser, but in the Edge browser, it defaults to "index.pdf."

Despite my attempts, I haven't been able to change this file name. Could you please assist me?

`...

    var objFra = document.getElementById(iframeName);

    if (isChrome || isOpera) {
        objFra.contentWindow.focus();
        objFra.contentWindow.print();
    }
    else if (isEdge || isInternetExplorer || isFirefox) {
        objFra.onload = function () {
            objFra.contentWindow.focus();
            objFra.contentWindow.print();
            return;
        }
        if (isEdge) {
            window.setTimeout(printDocument, 100);
        }
    ...}`

<iframe src="../../File/TEMP/e42c2279-1363-4d87-933f-625ff20eec7d/ExampleDocument.pdf#zoom=100&toolbar=0" class="m-3" style="height: 95% !important; width: 99%" frameborder="0" id="iDoc" name="iDoc"></iframe>

I expect the PDF file name to appear correctly here, just as it does in the Chrome browser. I tried changing the iframe title and other information, but I couldn't achieve the desired result.

Do you have any source indicating that the file name cannot be changed in the Edge browser? — Resul Bekir Şahin

I'm using an iframe, so there seem to be some points that don't align with the example you provided. I tried changing the title of the iframe, but it didn't have any effect. — Resul Bekir Şahin

When Chromiums like Opera or Chrome etc offer a filename to save a print it is sourced from the Page Title (usually the HTML <title> from a page holding an iFrame)

We can see that in the Developer inspection during print. Here the <title> has been extracted by Chrome from the PDF Metadata and used as the iFrame HTML <title>FPDF Editor Outpur</title> seen on the right and in the offered filename.

Edge does it different as it does not use the PDF Metadata but simply its own default index wrapper. <title>chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/edge_pdf/index.html</title> hence without any other title using print function, that is the offered name index.pdf.

There are other browsers apart from Chromium's and Mozilla's that may have other print defaults such as no default name.

However most Mozilla Fox based PDF viewers like R3D will simply use PDF.js viewer.pdf

Thank you for your help, but it seems that the situation is a bit different in ASP.NET. Although I provided a title, it didn’t appear. I gave your comment an upvote, but unfortunately, I still can't solve the issue.

I am changing the title of the main page, the iframe’s title, and the contentDocument’s title within the iframe, but unfortunately, it’s not yielding any results. I can’t figure out where it's pulling this index from.

I found that 'index.pdf' is coming from the title as you mentioned, but I don’t know how to modify it because this is a popup opened by the Edge browser.
