I was experimenting with scnanner and reset to factory default settings. And after that it does not read some barcodes.
I guess it might be the type of the barcode not supported by defautlt.
I am not sure how to make it scan again.
The barcode type as I see in PHP code is itf. But how can I make it support on that scanner?
This is entirely specific to this device. Please refer to the manufacturer's web site for such support.
