Short test mode
If the printer is turned on while the ( ON LINE > button is pressed, the
printer will enter the short self-test mode. The printer will start printing as
soon as the ( ON LINE ) button is released, and will print the version
number of the printer’s ROM, followed by six lines of the character set.
Each line will be offset by one character from the one before it. The final
result will be something like the following.

possible damage to the print head and/or platen.
