Web - Print dialog (Adobe PDF) is not displayed in Firefox 19

created 12 years ago

I didn ́t get the printer dialog in FireFox 19.0 and I can ́t print. This happens after the Windows Update!
When I run your demos I get the same result.
I come from Germany.
What is the problem?
Under IE 9 it runs like before.

regards

Steffen

    Hi Steffen,
    I have reproduced a similar issue locally. We will examine this behavior in greater detail and check for a suitable solution.

      Also reproduced in Firefox 19.0.1 (Czech version)

        Hi Steffen,
        We have carefully examined this issue and found that it is related to the fact that the native PDF viewer is always enabled in the latest version of the Firefox web browser. When the "Content-Disposition:inline" header is used, the PDF document is always sent to the native PDF viewer instead of the Adobe Reader. To solve this issue, enable the corresponding option in Firefox. See: [Alt]->Tools->Options -> Applications
        Portable Document Format (PDF) -> Use Adobe Acrobat option.
        It turns out that there is no special method to programmatically determine whether or not this option is enabled. This means that you need to configure Firefox manually.
        At present, we haven't found a suitable way to override the FireFox PDF viewer in our code.

            I have updated Alex' answer based on your comments. Please check the original answer.

              Just curious, has there been an update to this? We have a ton of Firefox users and would like an automated solution. Thanks!

                Hi D. Thompson,

                No, we cannot change the Firefox browser settings from our code. And the Firefox browser's native PDF viewer cannot correctly print the PDF document that was sent to the client after the "Print" button was pressed.
                So, the only solution is to change the default PDF viewer in the Firefox browser settings manually.
