When the Terminal sends data to the host, it sends it in the
following format:
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 802 RF Terminal transmits the data to the host, it will
be in the following format:
Terminal ID + T1: DATA + CR
or
Terminal ID + T2: DATA + CR
or
Terminal ID +T1: DATA + T2: DATA + CR

Zebra QL 320 Printer
The QL 320 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 320 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.
Each printer is shipped with a no charge roll of thermal paper that can be
used for development, including determining the exact label size that best
fits you needs and the capabilities of the printer.
