Chapter 3 Overview
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.
Figure 5. Bar Code Size/Height Requirements
Code V allows you to add a human readable data field to the bar code. Also,
you can specify a 1 or 3 dot gap between the human readable field and the
bar code.
When you insert a human readable field, the height of the bar code
automatically shortens. For example, you print a bar code that is 1 inch high.
Later, you add a human readable data field. The bar code height is 1 inch
minus the 1 or 3 dot gap and the text, which is 1/10 inch or 1/5 inch.
If the bar code height is less than the height of the human readable text, the
bar code height adjusts to the height of one dot. The gap and the human
readable text remain the same.
Horizontal bar code data is printed below the bar code; vertical bar code data
is printed to the left of the bar code. Figure 6 illustrates the readable data
adjustment feature.
