Does Bluetooth hardware print servers exist in nature?

Question

Bluetooth

Are there print servers in nature that allow you to connect a usb printer to a mobile phone, without a wife, a PC with an extended printer? The application only supports printing to a Bluetooth printer, but you need to force printing to a regular printer.

Answer 1

Of course they exist, but you can buy such junk right now, except on eBay.
It seems to me easier and cheaper to buy a printer with bluetooth.

Answer 2

The application only supports printing to a Bluetooth printer
. Now this has not explained anything.
More than a dozen variants of printers that are not compatible with each other fit this description.
Bluetooth is just transportation. But what is transmitted there?
Suppose there is a regular printer for restaurants (non-fiscal thermal printer). Just plain text without formatting. Such a forehead will understand the matrix and some of the old HP laser printers.
Modern cheap laser printers and inkjet printers will not understand. They are waiting for the finished image instead of the page.
