POS: How to auto-print invoice after validation (no PDF save, no backend code)?

Body:

In my POS system (Odoo), after clicking Validate , I want the invoice to print automatically — without saving the PDF locally or writing custom backend code.

Current behavior:

• Firefox: After validation, the invoice opens as a PDF in a new tab, automatically saved — I still need to manually click print.
• Chrome: After validation, a save dialog pops up — I have to save the file, open it, then print.

Desired behavior:

• As soon as I click Validate , the print dialog should open directly and print the invoice, without saving the PDF or requiring extra clicks.

I'm looking for a frontend-only solution (POS config, browser setting, etc.), not backend code.

Is this possible? Any suggestions on how to achieve this?
