Hello, I wanted to know more about the connections that can be made from the HW, my problem is that the pdf file is downloaded and to increase productivity I have the idea of connecting the printer directly to odoo. Are there possibilities to configure it somehow

I saw this solution, but is it the only one? Because it is to connect a single printer to make reports of the Sales module: Invoices, Budgets, Change Tickets.

IoT Boxes: I found this solution due to the question of how to print directly from the sales module. Are there possibilities in Odoo to make the impressions configuring in a different way without requiring the device? Since always when putting print it generates a pdf. Is there a way to connect the printer directly in Odoo?

In case an IoT Box is required (and there is no other solution) can several printers be connected? either to print tickets or invoices on A4 sheets.
The IoT Boxes serve from which versions? In my case I am using Odoo v14.
