STANDARD PRINTER COMMANDS
70 Copyright © 2006, Cognitive.
o
(lowercase letter O) Out of ribbon or
ribbon stalled. (Only reported by TT
printers capable of detecting a stalled
ribbon.) The printer sends this message
eight times per second if it runs out of
ribbon and USER_FEEDBACK is ON.
P
Printing in process, or printer paused
during batch mode processing.
S
Serial port communications error.
U
Printhead Up. The printhead is not fully
closed.
W
Waiting. The printer is paused during a
batch printing operation.
The printer sends a five digit number after each
letter. If the leading letter is a C (indicating the
battery is charging), the number following the C is
proportional to the battery charge state. If the
leading letter is an E (indicating an EEPROM
error), the number following the E is the EEPROM
checksum. In all other cases, the five digit number
shows the quantity of unprinted labels in the
current batch.
E messages have two parts. The first part begins
with an E and is followed by the calculated
checksum. The second part begins with an E and is
followed by the stored checksum.
NOTE: If the printer detects an EEPROM error, it will
automatically load the nonvolatile RAM with default
values. The printer may work, but print quality may be
degraded. Contact your service technician when an
EEPROM error occurs.
