 Evoked by occurrences listed under ‘Fault Messages’ in Section 6.2.

 Reprints the last label exactly, with no increment or time stamp changes; use it for error conditions. Always keeping this signal LOW will result in non-stop printing.
[4]
 Advances media until the signal goes HIGH and, if not in continuous mode, the media will be positioned at the next available media TOF. 
[5]
 If active with no current print job, “WAITING FOR DATA” is displayed. Specifying a quantity of 9999 while always keeping this signal ‘ON’ will cause non-stop label 
printing, except in single label mode (see Imaging Mode, Section 4.2.5), which will cause the printer to stop between labels; see Timing Diagrams, below.
