Thermal transfer media requires ribbon for printing while direct thermal media does not. To determine if ribbon must be used with a particular media, perform a media scratch test.
To perform a media scratch test, scratch the print surface of the media with a fingernail or pen cap. Press firmly and quickly while dragging it across the media surface.
Direct thermal media is chemically treated to print (expose) when heat is applied. This method of testing the media uses friction heat to help identify the media.
