Bar Code Command Set
Notes:
1. If bar codes with human readable interpretation (HRI) are placed too close to
the page edges, the human readable characters may fall outside the physical
medium boundaries. If the HRI falls outside the physical medium
boundaries, the characters may not print.
To ensure that the human-readable characters print, choose X and Y
parameter values that allow sufficient space for the characters to print.
Some guidelines are:
For bar code types UPC-A, UPC-E, EAN-8, and EAN-13, choose X and Y
coordinates that place the bar code at least 1/6-inch. from both the top
and left edges of the page.
For bar code types UPC Two Digit Add-On and UPC Five Digit Add-On,
choose a Y coordinate that places the bar code at least 1/6-inch. from
the top edge of the page.
For Codabar bar codes, the data must include the START and STOP
characters.
For Code 128 bar codes, the table on the following page should be used
to determine the hex value of the desired character.
2. The symbol reference point must be inside the bar code medium
presentation space and must lie within the logical page.
