Summary
If your library has a barcode reader, but barcodes are not appearing in the DPX GUI, follow the steps below.
Resolution
UNIX:
Edit dpx/bin/ssjuker and append '-b on' (without quotes) to the listed data, so that it looks like:
exec ./juker -C 256 -b on
Windows:
Edit the HKLM/Software/Syncsort/BackupExpress/<hostname>/0/SSJUKER string value in the registry so that it reads:
-C 256 -b on
Then exit the GUI (if it is open), stop and start the cmagent, and bring up a new GUI. The barcode labels will now appear.
