* Thermal printer runs high transient current for printing. For this reason, it is recommended to
use such a power supply that has high response performance to guarantee print quality, in
addition, that support high peak current to run.
* When power supply cable is excessively long and small in diameter, the voltage drops to
cause error by wrong voltage sensing. To avoid this type of error, make sure to use proper size
of cable. The size recommended is less than AWG#18. If such a cable is not available, connect
the cable near the printer and place low ESR condenser between 2200~6800micro.
