[Description]
• Executes a test print with a specified test pattern on a specified paper.
• pL and pH specifies the number of the parameter such as n, m to (pL + (pH × 256)) bytes.
n specifies the paper to be tested.

[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.
