Thank you for the review and comments about the POS being a great and smooth plugin. We love hearing this feedback.
We’d like to confirm, both these features you highlight as missing are supported for the POS as main features. 🙂
Printable Invoice. Using our Print Manager add-on plugin the POS supports 3 default print templates: Order Receipt, Customer Receipt and Customer Order Receipt. Plus, we support the ability to develop custom print templates.
Barcode scanner. The POS provides a Barcode field to the product details page under inventory. In the POS view, the Barcode number can be searched manually, or you can connect a Barcode reader and scan products. Barcode scanned products can be automatically added to the cart. We also support an iOS and Android app, which includes a scanner using the camera of the device.
I hope that clarifies the POS support for these two main features.
