Chapter 2 Bar Codes
Human Readable Line (HRL)
The human readable line, which is .10 inch below the bar code, will print in
any of the available fonts as long as the bar code is not rotated. (Rotated bar
codes use a special font.)
To enable bold, underlining or expanded print on the human readable line,
you must first print the bar code without the line. Exit the bar code mode.
Then, print the line in normal text mode with the specified enhancements.
Spacing Between Bar Codes
The space before and after a bar code is referred to as the “quiet zone” and
equals .25 inch. If two horizontal bar codes are placed side by side, the
designated minimum distance between them is .50 inch.
You can insert commas, spaces, and horizontal tabs as delimiters to separate
the bar codes:
• comma - no extra space added
• space - adds .10 inch for a total .60 inch quiet zone
• tab - adds appropriate number of empty spaces to reach next tab
Examples
The comma does not add any space; therefore, only .50 inch separates the
bar codes.
A space character adds .1”. You can insert multiple space characters.
