Provides 5 V (±10 %) power supply to external
devices.
The maximum current that can be provided is
180 mA.

O power supply, while also keeping Signal
Ground and Frame Ground separate.
Sends an instruction to start printing.
• In pulse mode, printing starts if a change from
High to Low is detected. Detection occurs
only when the state of the "End print" signal is
High, and does not occur while printing is in
progress.
To print a new label, first return the signal to
High, and then change it again from High to
Low.
• In level mode, printing starts if this signal is
Low. Detection occurs only when the state of
the "End print" signal is High. Printing of new
labels will continue until Low is detected.
• Signal logic: Low active
