# Prints a series of black bars with increasing "heat time" settings.
# Because printed sections have different "grip" characteristics than
# blank paper, as this progresses the paper will usually at some point
# jam -- either uniformly, making a short bar, or at one side or the
# other, making a wedge shape.  In some cases, the Pi may reset for
# lack of power.
#
# Whatever the outcome, take the last number printed BEFORE any
# distorted bar and enter in in Adafruit_Thermal.py as defaultHeatTime
# (around line 53).
#
# You may need to pull on the paper as it reaches the jamming point,
# and/or just abort the program, press the feed button and take the
# last good number.
