Zebra Technologies R-140 - Manual (Page 11)

Print Mechanism Capabilities
The Zebra R-140 print mechanism has been designed to print information
on labels, tickets, and tags. It uses a square or rectangular dot thermal
printhead that heats a ribbon as it passes beneath the print elements, melting
its ink onto the media (direct thermal print mode involves using
heat-sensitive media instead of an inked ribbon). Print speeds are selected
via software control.
RFID Capabilities
Transponders used with the R-140 work on the 13.56 MHZ international
frequency for RFID. Currently, smart labels based on chip/antenna inlays
using Texas Instruments’ Tag-It  , and Philips Semiconductors’ I • Code 
RFID transponder chips are fully supported. Transponder data may be read,
written and write-verified through RFID enhancements to Zebra’s ZPL II
programming language. Encoding and verifying data through ZPL II is as
easy as printing a bar code.
Media Transport Mechanism Capabilities
The media transport mechanism of the Zebra R-140 printer has been
designed to accommodate various types of media including die-cut labels,
ticket and tag stock, continuous roll media, fanfold media, and black-mark
media.
System Requirements
In addition to the Zebra R-140 printer, you will need the following items to
form a complete label preparation system:
n
Label-, ticket-, tag-, or “Smart” RFID label-stock
n
Thermal transfer ribbon (if printing in Thermal Transfer mode).
