Do I need to use ribbon?
The media itself determines if you will need to use ribbon.
The easiest way to find out is to scratch the surface of the media rapidly with your fingernail. If a black mark appears where you scratched, the media is Direct Thermal, so you do NOT need ribbon.
What kind of ribbon can I use?
This printer can use ONLY ribbon coated on the outside, unless you purchase and install the optional spindle that allows the use of ribbon coated on the inside. Contact your authorized Zebra reseller for ordering information.
