• This command is only valid when processed at the head of a
line during the STANDARD MODE.
• The command will be ignored in PAGE MODE.
• During macro definition, if this command is processed, the
macro definition is suspended, and the command starts being
processed.
• Printer will reset its hard disk after finishing test printing.
Therefore, the printer makes download characters, bit map
images and macros undefined, clears the reception buffer/print
buffer, and returns the various settings to defaults. At this time,
the DIP switches are read again.
• Paper cutting is performed at the end of test printing.
• Printer will be BUSY when the processing of the command
starts.
