Disable adobe reader from showing up from java process

Hi all, Im been here before but I have to create new username for new email. My old email no longer valid

I would like to ask something about adobe reader.
Me and my team are currently as a technical IT team for web-base-system.

So our current user are sometime producing reports from any data that they collected.
As far from my knowledge ( I'm not programmer of the system ), when our user click the "Print" button on the system, all data shown on the screen will be converted to pdf form. I can see that this is a Java process because the java applet are running ( java console also shown ).
In the console, I can see that the system are exporting the data into temporary pdf file and execute java process to "Print" that temporary pdf file.

The thing here is, user would like to remove/disable pdf pop up when everytime they press Print button.
The pdf pop up will exit the Full Screen view for the browser. I've been trying to find any guide on internet, but it only help to disable Splash Screen. I don't want the any adobe reader shown on the screen like image below.



Anyone have idea how do I disable the grey adobe box everytime user click print button?
Or this have to do with some programming in the system?

As far as I see, this seems to be a bug in the "printing" routine you're using. Moreover, using a Java plugin just for this is overkill and bad practice. As an experiment, what happens if you disable the Java applet in the browser? Does it still generates the pdf and opens Adobe Reader?

It seems that the Java applet is doing something that shouldn't be done as most likely it's launching the external program. A solution would be to review that part of the system (which involves programming, of course).
Ideal solution, however, is to modify the system to generate the pdf server-side. On clicking the button, the server will call whatever libraries are necessary for that (even Java, but server side, without applets) and offer the final file as a standard download for the browser to use as usual. This is more drastic change, but users will get a more natural interface, much like the entire web is generally used.
