5–81 Bar Codes
Hn[.m] Optional parameter to adjust the overall height
(vertical expansion) of the bar code symbol (including
the upper and lower 0.1–inch guard bands and any
human readable data).
Height adjustments are made in 0.1–inch increments;
enter H and a value from 4 to 99 to select height
adjustments from 0.4 to 9.9 inches. The default value is
0.9–inch.
.m is an additional number of dots for the bar code
height. (Dots are in the current dot scale.)
BFn;L Optional parameters for assigning a dynamic bar code
data field location on a form and for designating the
length of the data field. With these parameters, the
actual data for the bar code data field is dynamically
provided during the Execute Form Mode; the data is
not specified during the Create Form Mode. To use this
field, perform the following steps:
a. Enter BF.
b. Replace n with a number ranging from 1 to 255
to identify the bar code field. The SR and SC
parameters specify the exact location of the bar
code field identified by n.
c. Replace L with a number equaling the total
number of characters in the field. (The actual
data provided dynamically during the Execute
Form Mode can be less than L.)
d. The information for the data field is entered
dynamically during the Execute Form Mode.
(Refer to “Execute Form: Dynamic Bar Code
Data” on page 4–55 in the “Commands”
chapter.) Do not use the data field parameter to
enter data when the BFn;L parameters are used.
However, refer to the data field description for
available characters.
DARK Optional parameter to produce darker looking bar
codes. Enter DARK. Refer to “Dark Printing” on page
4–10 for more information.
