(figure 1). Two pieces of identifying information are recorded
on the print wheel by using two stopping elements, such a recess
37 having side edges 38 and 39 disposed at angles "1 and "2 with
respect to the slot 17 (figure 3). In the case of figure 3, the
print wheel is rotated to the left and right to determine the
identity codes "1 and "2 (figure 5), where the degrees are
measured by counting clock pulses provided by scanning markings
on a clocking disk on the printer wheel. With the aid of the two
recorded identity codes "1 and "2, the control device
(microprocessor) 35 in figure 4 obtains identification data from
the memory 36 required to control print intensity, ribbon
advancing step width, and other parameters of the printing device
for the newly inserted print wheel (col. 8, lines 1-6). Thus,
the operator need not perform any additional settings when a
print wheel is exchanged for a new print wheel since the printer
functions are automatically adapted to the set of type faces
carried by the newly inserted print wheel (col. 6, lines 28-33).
The printing parameters in Bruns are stored in the
microprocessor memory and are never printed out. The identity
codes "1 and "2 are "recorded" on the printer wheel as angles
between a slot 17 and stopping elements, but are never "recorded"
in the sense of being printed out and are never part of anything
which might be considered indicia. The identity codes "1 and "2
are used only to retrieve the printing parameters from memory for
