Determining the Barcode Label Type
Achecksumcharacterisan“invisible”character—readablebythebarcode
reader,butnotshowninthehuman‐readabletextonthelabel.Itsfunction
issimilartoaparitycheck.
SeeBarcodeLabelSpecificationsonpage553fordetailedinformation
abouttherequiredphysicalcharacteristicsofbarcodelabels.
Report right-hand
characters
Youwantthelibrarytoreportonlytheright‐mostxcharactersinthebarcode,
wherexisanynumberfrom1to16.Thisisthedefaultsetti ng.
Forexample,ifthebarcodeis1234567L2andyouconfigurethelibrarytoreport
the5right‐mostcharacters,thelibraryreports
thebarcodeas567L2.
Important: Be careful when specifying the number of right-most characters to
report. You may end up with duplicate barcodes reported. For example,
1234567L2 and ABCD567L2 are both reported as 567L2.
