SSL Handshake failed error when printing

[Nightbringer01]

I'm having issues using a https site with a local installation of QZ tray.

The application keeps returning SSL handshake failed. The connection works, but when I print anything it just throws the SSL handshake failed.

This is covered in part here: https://qz.io/docs/faq#pkix-build-path-failed

Java isn't really that great about using the system proxy, so workaround often includes fetching the resource using AJAX with the browser and sending it to QZ Tray using Base64 format.

I'm not sure if I just haven't gone through the provided document enough, but I dont think the error I have is in the document.

It's a java.awt.print.PrinterException

here's a snippet of the log file:

@Nightbringer01 yeah you're right, this one is failing inside of JavaFX, but I believe the underlying cause is still certificate related.

- [ERROR] 2023-09-10T23:26:37,329 @ qz.utils.PrintingUtilities:214
- Failed to print
- java.awt.print.PrinterException: SSL handshake failed

... if you fetch the HTML content using $.ajax(...) or fetch(...) and use flavor: plain, I would expect this issue to go away. Of course, this can cause other issues (such as relative links breaking).

JavaFX should inherit the same certificates as Java, so the cause and resolution I would expect to be the same as mentioned, albeit surfacing as a different symptom.

[Nightbringer01]

Yup the work around works, changed my code to this:

/// Pixel Printers ///
    function printHTML(html) {
        var config = getUpdatedConfig();

        var printData = [{
            type: 'pixel',
            format: 'html',
            flavor: 'plain',
            data: html,
        }];

        return qz.print(config, printData);
    }

    async function printURL(url) {
        var config = getUpdatedConfig();
        const response = await fetch(url);
        const htmldata = await response.text();

        return printHTML(htmldata);
    }
