This test is a simple check of the display and printer. On entry, a series
of characters should scroll across the display (and a single line of
the same characters should print out on the printer). The characters

matrix. This makes it possible to distinguish any dots that no longer
work, on the printer as well as the display.
Press STOP to exit to the test menu.
