When the Terminal sends data to the host, it sends it in the
following format:
RF Terminal ID + DATA + CR
Typically, the data is simply a string of characters, but in the
instance of data coming from the magstripe reader, there are some
additional characters you need to be aware of. The magstripe
reader sends its data in the following formats:
Track 1:
T1:
DATA
Track 2:
T2: DATA
Track 1&2:
T1: DATAT2: DATA
So, when the RF Terminal transmits the data to the host, it will be
in the following format:
RF Terminal ID + T1: DATA + CR
or
RF Terminal ID + T2: DATA + CR
or
RF Terminal ID +T1: DATA + T2: DATA + CR

Zebra QL 3 Printer
The QL 3 Printer is used for label printing. It doesn’t have Magstripe input.
The classic application is for printing shelf labels during shelf price
verification:
1. The operator scans a shelf label.
2. The Terminal transmits scanned data to the host computer.
3. The host computer looks up the price, description, etc. and
transmits the computer price back and sends the necessary
commands to the attached QL 3 printer to prints a new shelf label
with the correct price.
4. The terminal operator then peels off the label and applies it to the
shelf.
