quiry) and determines that there are four Bluetooth devices in the vicinity.
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 initiated and processed without any operator intervention, much like the IrDA system described previously.
