[Description] • When a hexadecimal dump is printed by this command, the data transmitted after
the command may not be printed, because the printer clears the receive buffer.
To avoid this, transmit data from the host after the printer prints the starting
message of the hexadecimal dump.
• This command is enabled only when processed at the beginning of a line in
standard mode.
• After the test print is finished, the printer resets itself automatically. Therefore,
the already-defined data before this command is executed, such as 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.
• At the end of the test print, the printer cuts the paper, or ejects the cut sheet
when the cut sheet is selected.
• The printer goes BUSY while this command is executed.
