Examples; Bar Code Size/Height Requirements - Printronix L7032 Programmer's Reference Manual

Chapter 3
Overview

Examples

Using different printers may affect the printed appearance of your print
samples compared to those shown in this manual due to the printer's scaling
factor and varying print mode/densities. Print position also depends on your
paper top-of-form position and the initial print position. Therefore, the location
of the bar code print samples in this chapter are for reference only and do not
reflect the actual bar code print position.

Bar Code Size/Height Requirements

The length of any bar code is based on several factors:
(1) the type of bar code
(2) the number of data characters encoded
(3) the bar/space ratios
The starting position of a bar code is determined by any justifications
specified in the previous alphanumeric command.
The alphanumeric command provides the proper length (height) of the bars in
bar codes.
For horizontal bar codes, the graphics height command specifies bar code
height; for vertical bar codes, graphics width specifies bar code height. Bar
code height/width parameters are specified in the two-digit extended graphics
command. A decimal point is automatically interpreted between the first and
second character digits.
