Print a PDF with JavaScript without dialog or with fixed settings

Question

I'm a newbie with JavaScript and I was looking for a method to print a pdf document with a button click without any dialog window opening or not make the user able to change the print settings, I want to print it with a fixed printer, number of pages and format.

I already tried Print.js but it still opens a dialog window and the user can change the settings in it.

TLDR: It's not possible. That would pose a serious security risk. — War10ck

Due to security concerns, browsers will not allow you you to print without consent. Or saving without consent. If the browser has the settings to download without a popup window, then you might be able to locally create a file on the server side and then saving it. Also, a while back I had a similar issue, but I needed it to be local on one system only. So I created a simple C# program to create a document, save it as PDF, open it in Adobe Reader (hidden window), and sent to the printer. — KingsInnerSoul

The browser does not allow it to print automatically without the user being able to choose the settings to print. This would be extremely problematic as someone can print endless pages without the users permission

@Cris The word you're looking for is "with"; I edited your post and changed them all. "whit" is a word, but it means something completely different. But as the duplicate I posted says in its answers, there is no way of interacting with the printing process other than initiating it. You can suggest things like paper size and orientation, but that's it.
