One last tip regarding POS systems: POS systems are usually
personal computers that “look like” ECRs; whereas, ECRs are
hardware devices that are dedicated to ECR use and are not as
flexible and upgradeable as PCs. Because POS systems are PCs in
disguise, they need an operating system (like Windows
®
XP) and an
application (like Microsoft
®
Word) that allow it to function as an ECR.
There are a very large number of applications or “software packages”
that are available for POS systems and these are not always written by
big companies that have vast experience in the POS field. Because of
this fact, you may need to check with your software supplier/publisher
for support regarding further scanning errors. In closing, we would like
to mention that most if not all scanning troubles are due to improper
scale programming and improper ECR/POS programming; the later
being the more common.
