throughout the scanning period. The scan should be at right
angles to the bars of the bar code. However, HUNTER tolerates a
considerable variation in the scan technique.
The scan can be slow, fast, traversed across the bar code in an
arc rather than a perfect straight line, or even scanned in a
'wavy' line, provided that the wand remains within the bar code
region. HUNTER will allow both Code 39 and EAN 8/13 bar code
types to be scanned either left to right or right to left,
NOTE 'Code 39' is the trademark of Intermec Corp.
It is not necessary to place the wand precisely at the beginning
of the bar code before a scan since HUNTER will work out which
information transmitted from the wand actually corresponds to
the bar code itself. If the wand is resting on a bar code, it
i's possible to move the wand to either end of the bar code and
then scan in the opposite direction. HUNTER will then work out
the beginning and end of the bar code.
HUNTER will allow a maximum of 16 characters to be represented
by a Code 39 bar code. This should be borne in mind if the
reader intends to produce his own Code 39 bar codes. If larger
codes are required, contact HUSKY Computers for details.
