Extensions, UPC A, PostNet. Each of these is identified with a numeral or a letter that coincides
with the parameter to be inserted in the ^Bx command on page 18 (see table 8).
Each type of bar-code has its own characteristics: some are fixed length, others not, some accept all
characters, and others only upper case letters or numerals.
The widths of the bars are defined according to set ratios. Some bar-codes require a fixed ratio to be
read properly, while for others the ratio can vary from 2 to 3 without affecting the reliability of
readings.
