STANDARD PRINTER COMMANDS
24 Copyright © 2006, Cognitive.
Comments Unless modified by a BARCODE_FONT command, all codes
except UPCA+, EAN8+, EAN13+, and UPCE use an 8x8 font
for bar code subtext. The excepted codes use a 5x7 font, to
allow space for extender bars. Bar code subtext begins
two dots below the bar code block.
All bar codes are positioned independently. This includes
ADD2 and ADD5, which are normally used as add-ons for
UPC and EAN codes. The programmer is responsible for
the proper placement of all codes, including add-ons.
MAXICODE and PDF417 codes differ considerably from
other bar codes. See BARCODE UPS and BARCODE
PDF417 for programming information.

IMPORTANT!
Follow the rules of the bar code in use. For example,
UPCA and several other codes do not support characters
A-Z. Attempting to print unsupported characters will
produce bar codes that will not scan. Incorrect bar width
ratios can also produce unscannable bar codes. Please
refer to Chapter 10 - Bar Code information.
Character darkness and pitch also affect the reliability of
the bar codes. Avoid printing bar codes having bar widths
of less than 10 mils. Rotated bar codes should not be
printed with bar widths of less than 15 mils.
