Human-Readable Line (HRL)

The human-readable line is printed 0. 10 inch below the bar code
symbol. The height of the HRL and the 0.10 inch space are not

included in the bar code height parameter (p2).

A diamond symbol appearing in the human-readable line indicates
one of the following conditions:

• Margin overrun. The data to be printed exceeds the available space
remaining inside the programmed margins.

• The DEL character has been received while printing in a bar code

style that permits the use of all 128 ASCII characters.

• An invalid character has been received. An example of this would be
a letter "A" sent to the printer while printing a style 5 bar code.
Style 5 (EAN-8) only accepts the digits 0-9.

Font Styles and Enhancements

Non-rotated bar codes can be printed with an HRL in any of the fonts
available to the printer.

If enhancements are desired (e.g., bold, underline, or expanded) the

HRL must be printed using the normal text mode. Print the bar code
symbol(s) without the HRL first. Exit the bar code mode and print the
HRL using the normal text mode with enhancements.

Rotated bar codes use a special font for the human-readable line.

Spacing and Bar Code Editing Aids

There is a 0.25-inch space called a quiet zone at the beginning and
end of every bar code. As a result, the minimum distance between
two horizontal bar codes is 0.50 inch.

Most bar code styles accept commas. spaces, and horizontal tabs as

delimiters to separate bar codes. A comma adds no additional space
between bar codes, so the separation is the width of the quiet zone or
0.50 inch. A space character adds 0.10 inch to the quiet zone for a
total of 0.60 inch separation. A horizontal tab adds the appropriate
number of empty spaces to go to the next tab.
