Hello, I'm using community version of Odoo, I just want to ask if there is a free Barcode Scanner and Barcode / Qr Printer free?, We're using Cyborsys's Barcode. 

We're trying to re-create the video of Efficient warehouse management with barcodes - Odoo Inventory, is there anyway we can do it in Odoo community using all free apps? ​ ​ ​
