[Details] This command is enabled only when processed at the beginning of a line in standard mode.
This command is no effect in page mode.
When this command is received during macro definition, the pr inter ends macro definition and
begins performing this command.
After the test print is finished, the printer resets itself automatically. Therefore, the
already-defined data before this command is executed, such as an user-defined characters,
downloaded bit image, and macro, becomes undefined, and the receive buffer and print
buffer are cleared, and each setting returns to the default value. The printer also re-reads
the DIP switch settings .
The printer cuts the paper at the end of the test print.
The printer goes BUSY while this command is executed.
