the cursor pointing to the non-“xx” character.
E6 Example: Remove zeros at the beginning of barcode data
This example shows a barcode that has been zero filled. You may want to ignore the zeros and send all the
data that follows. E6 searches forward for the first character that is not zero, then sends all the data after,
followed by a carriage return. Using the barcode above:
Command string: E630F10D
E6 is the “Search forward for a non-matching character” command
30 is the hex value for 0
