Hello Gimi
The Sharp XE-A207 does not support a barcode scanner. Therefore, choose the Sharp XE-A307 model. Another main difference between these two types is that the XE-A307 model has a 2 paper roll.
For programming, the models are the same. The best way is with a laptop and SD card. Greetings RF

We don't use a barcode scanner. We do not know.
