Printing Web Page Without Print Preview - javascript

How can I get a code to print a page using js.
Note: I don't want to take print preview and then print. - once I click, it should print the page.
Page is containing text and image.
I need to have a link for printing the current page.
Once I click it should fetch the data and print.
(without showing content in nextpage as print preview and then requesting to press print option)
using: window.print()
its getting me to print preview page and I have to press print option from browser - right!
I need to print once I click or during page load.

As far as I know this is not possible. Security reasons come to the mind - it would mean the peripherals of the computer are directly accessible from the web page code.

Oracle apex open file browser automatically on page load

I need to open "File Browse" item ("P50_BLOB") on page load.
I tried clicking the item with dynamic action on page load with javascript:
$('#P50_BLOB').click();
it didn't work, though it does work using the console.
I have also tried using async / wait / promise / wait for document to load.
I even tried to do it with another apex item that will make that click when it is changed, and manually changing the item is working, but on page load it's not.
This is supposed to be very simple but nothing works.
Thanks.
If you try that with the developer tools open in Chrome you will see an error:

Print a PDF with JavaScript without dialog or with fixed settings

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.
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

Print PDF.JS without print btn

I can see a pdf.js document in a digital viewer. Is it possible to print it without seeing a print button or the hotkey?
If I print with the browser function of printing, its just that one page, that I see.
I need it without the whole border stuff, just like the pdf and every page, not just what I see.
If I could have access to the original pdf somehow, this would be fine too.
Extension in FFox enabled right click again and then I could print the iframe to pdf

How to create a print dialog that displays the current web page's screenshot

I just want to know if there's easy way to create a print dialog for WordPress that outputs on the print dialogue box the actual view of a webpage. P perhaps a full page screenshot might work as long as it has the full page's height.
I tried WP-Screenshot plugin on this page. The plugin outputs a screenshot that can be printed out by adding a print dialogue plugin. However, the the height of the image produced by WP-Screenshot can't be dynamic so I guess I need to find another solution.
I can't find a plugin that has the functionality to print the current webpage with all the styles preserved in the print dialogue. So I'm thinking that screenshot might work.
Any idea or suggestions?
For printing the page and getting print dialog you can simply use window.print()
For better understanding please visit window.print()

Check your browser settings. JavaScript does not control this.
