[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 printer 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.
