Options are:•1D Quiet Zone Level 0 - The engine performs normally in terms of quietzone.•1D Quiet Zone Level 1 - The engine performs more aggressively in termsof quiet zone.•1D Quiet Zone Level 2 - The engine only requires a quiet zone at the endof bar code for decoding.•1D Quiet Zone Level 3 - The engine decodes anything in terms of quietzone or end of bar code.1D Quiet Zone Level 01D Quiet Zone Level 1*1D Quiet Zone Level 21D Quiet Zone Level 3
