[Notes] • This command is enabled only when processed at the beginning of a line in
standard mode.
• This command has no effect in page mode.
• 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, and downloaded bit image, 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.
• At the end of the test print, ejects the cut sheet when cut sheet is selected.
• When slip is selected, this command is executed after the ejection of the paper.
• The printer goes BUSY while this command is executed.
