provides the checksum, the printer will check that it matches the expected checksum. If it does not
match, the printer will print all zeros and the expected checksum. See Appendix P.
Valid bar widths: The fourth character of record is the width of the narrow bar in dots. All other bars
are a ratio of the narrow bar (2 times, 3 times, and 4 times the narrow bar width).
