Scanner beeps at some bar codes and NOT for others of the same bar code symbology.
The print quality of the bar code is suspect.
Also check character length lock.
The aspect ratio of the bar code is out of tolerance.
Check print mode. The type of printer could be the problem. Change print settings. For example change to econo mode or high speed.
