Print a Continuous Slip
This test prints several lines of data that show the settings for the functions set in level 1
diagnostics, then prints the character sets in all the possible variations as long as slips are
fed into the printer. This is similar to the information printed on the receipt during the
receipt test. See the sample printouts at the end of this chapter.
Caution: The DIP switches are pre-set at the factory and should generally not be changed.
If you must change them, do so carefully to avoid changing other functions.
