∗1 Input and output directions are described as viewed from the printer.
Input: Signal input to the printer from an external device.
Output: Signal output from the printer to an external device.
∗2 The logic for all output signals can be reversed.
The information provided in the Description column is based on the default signal logic.
If the signal logic is reversed, it will be the opposite.
∗3 Except for the "Start print" signal, the logic for all input signals is low active. (The logic for input signals cannot be
reversed.)
∗4 The "Start print" signal and "End print" signal can be switched between pulse and level. Therefore, there are 4
possible configurations for the "End print" signal: [Pulse or Level] x [Low Active or High Active].
∗5 The results of the previous nozzle check are applied to the clogged nozzle detected signal (pin 24). Therefore,
during a nozzle check, issue a nozzle check command (pin 14) before checking the clogged nozzle detected signal
(pin 24). Refer to timing

Level Indicates whether the printer has detected a
clogged nozzle in the head.
• L: Clogged nozzle detected
• H: Clogged nozzle not detected
* The results of the previous nozzle check are
applied.
* Even if nozzle clogging is not specified (when
a nozzle check is not performed, or if a warn-
ing occurs while the state of the nozzles is
unclear), the value at that time is maintained.
Level Indicates whether the printer is in a paper out
state.
• L: Paper out
• H: No paper out
