STANDARD PRINTER COMMANDS
Copyright © 2006, Cognitive. 69
R
Ready. The printer has no pending print
tasks, is not charging, and the background
buffer is empty.
The printer can send many other status messages
to the host in response to error conditions, but the
printer communications port will go busy in the
event of a printer error. Therefore, the printer will
send the following error messages but will not
respond to the QUERY STATUS command if these
errors occur:
c
(lowercase letter C) Cutter error
(applicable only to cutter equipped
printers). The label cutter is jammed or
not working correctly.
D
Download error. An error has occurred
while attempting to load new firmware.
E
EEPROM error. This error will occur
when printer is first turned on if the
EEPROM checksum is invalid.
H
Hot printhead. This error will occur if the
printhead thermal cycles.
I
Nonvolatile memory failure.
L
Low battery. The printer sends this
message eight times per second if it
detects a low power condition and
USER_FEEDBACK is ON. The printer will
send this message once regardless of the
USER_FEEDBACK state if the power drops
below the normal operating voltage level
(for example, when the power is switched
off).
O
Out of paper. The printer sends this
message eight times per second if it runs
out of paper and USER_FEEDBACK is ON.
