2. Joe’s Terminal queries each of the four nearby devices to de-

termine which services they provide (a Service Discovery).   The

Bluetooth enabled QL 320 “Sandy’s Printer” offers the printing ser-

vice.

3. Joe’s Terminal sends a print connection request to Sandy’s

Printer.

4. Sandy’s Printer evaluates the request and determines that

Joe’s Terminal is permitted to use the print service, 

but only if the

correct password is submitted.

5. Sandy’s Printer queries Joe’s Terminal for the password (Au-

thentication).

6. Joe’s Terminal returns the correct password and the print con-

nection is established.

7. After Joe’s Terminal is finished printing it disconnects with

Sandy’s Printer. (Some Bluetooth services disconnect automati-

cally, others must be closed manually.)

There are several layers of security in the Bluetooth system, so

this sequence may not be a completely accurate representation of

how your printer may function in a Bluetooth environment.  For the

most part, communications using the Bluetooth protocol are initi-

ated and processed without any operator intervention, much like

the IrDA system described previously.
