A printer with Bluetooth receives all the data to be printed via Bluetooth. But what I would like to know is, how the data from the Bluetooth module is transferred to the printer. Is it through the I/O pins in the Bluetooth module? If not how?

Also, a Bluetooth module consist of I/O pins through which information or data is transferred. How many I/O pins can one Bluetooth module can have at maximum?
