Barcode Settings
The LS-100 can print 3 different barcode styles: UPC-A, UPC-B, and
EAN-8. UPC-A is a 12 digit barcode and has been the predominant
standard in the US. UPC-B is a 13 digit barcode that is usually
employed whenever total prices exceed 4 digits. Finally, EAN-8 is an 8
digit European barcode that is equivalent to 8 digit UPC barcodes used
in the US. EAN-8 is usually used to label very small packages. The
LS-100 defaults to UPC-A barcodes. The reason for this is that 90% of
all applications will employ this barcode. Only if you are very
knowledgeable in barcoding, should you attempt to change any of
these settings. Many “scanning trouble” errors can be attributed to
improper barcode settings. Please read the next section carefully.
Common Barcode “blues”:
The barcode is a complex and continuously evolving creature; there
are volumes upon volumes of books relating to barcodes. However,
with respect to price computing printing scales, there are a few simple
rules to follow to minimize barcode errors.
First, read the
PLU Creation Guidelines in PLU Programming, PLU
Create & Edit section. Keeping PLU numbers equal to UPC Codes
equal to ECR/POS PLU numbers will eliminate a great number of
problems. Secondly, try to coordinate the scale programming and the
ECR/POS programming. Many times there may be more than one
party involved and their failure to communicate properly may result in
errors later on. Finally, make sure that the ECR/POS system is set up
to be able to understand UPC-A barcodes. UPC-A is also known as
UPC-12, price embedded barcode, or random weight barcode.
If you have followed all of our directions but you are still having trouble,
then the trouble is most likely on the ECR/POS side. You need to
make sure that all of the ECR/POS scanner settings are correct as well
as ECR/POS PLU data and settings. If the barcode scanner beeps,
this is a sign that the scanner is functioning properly; most if not all
scanners should be able to read any barcode printed by the LS-100.
Because of this, the scanner should never be the source of barcode
troubles unless the output data of the scanner is being rejected by the
ECR/POS system; in which case, you must coordinate your scanner
with your ECR/POS system.
