A communication error occurs when printing via serial cable (RS-232C).

The communication settings between your computer or host device and the printer may not be configured correctly. With the P-touch Template Settings tool, you can specify the initial printer settings according to the host system environment or the host device that the printer is connected to. You can download the P-touch Template Tools from the [Downloads] section.
