On button Click PDF printing to client's printer without opening PDF in browser

I have a requirement in the Axelor based web application as follows:

I have already generated PDF files and saved on server, also their entries are saved in database in dms_file and meta_file tables.

Now requirement is that there should be a « Print Attached Documents » button on my page. When this button is clicked, just printer selection dialog will open for selection of printer, and then document should be printed directly to printer. I don’t want to open each PDF individually and click on PDF Viewer’s Print button.

I am searching and struggling for many days, but I am unable to figure it out.

Need urgent help.
