If a barcode includes a Tab, Carriage Return or ESC encoded but the scanner does not respond to it, the scanner may need to be configured to enable invisible characters.

Scan the Enable Invisible Characters barcode in the printed sheet to enable invisible character scanning.
This configuration applies to the following scanner models: WWS100i, WWS550i, WWR2900 (with Firmware FM3-b-1.03-IN or newer. Firmware starting with AMC is older and may not work), WCS3950, and WLR8950.
