This add-on enables POS to read and print tare barcodes. We print a barcode tare label to sell loose goods in a Bring Your Own Container (BYOC) scheme.
This add-on enables POS to read and print tare barcodes. We print a barcode tare label to sell loose goods in a Bring Your Own pot (BYOC) scheme.
The BYOC scheme has four steps:
1. The cashier weighs the container and sticks the tare bar code onto the customer's pot.
2. The customer takes the desired quantity of the goods s-he wants to buy.
3. The cashier weighs the filled container and goods, and POS gives the corresponding price.
4. The cashier scans the tare bar code, and POS removes the container's weight from the latest product of the order.
The BYOC scheme has five steps:
1. The cashier weighs the pot and sticks the tare barcode onto the customer's pot.
2. The customer go and put loose goods into the labeled pot.
3. The cashier weighs the pot with loose goods inside. POS computes the price including the pot.
4. The cashier scans the tare barcode. POS get the pot weight from the barcode. POS subtracts the pot weight from the weight of the latest product. POS sets the billable price for the loose goods.
5. The customer pays.
This add-on adds a news screen to POS to print (web) the tare barcode labels. This add-on enables POS to read a tare barcode. Reading a barcode makes POS adjust the weight of the latest article in the order list. The new weight is equal to the total weight minus the tare weight. The price is updated accordingly to the weight change. This add-on adds a news screen to POS to print (web) the tare barcode labels. This add-on enables POS to read a tare barcode.

Install this add-on and configure the point of sale where you want to be able to use the tare barecode. Setup the default barcode sequence ID according to your barcode nomenclature. The label printing is done using web print. To streamline the label printing it is advised to use the silent printing mode (firefox) or the kiosk printing (chrome).
The command line to start a chrome base browser in kiosk mode with silent printing looks like:
``chromium-browser --use-system-default-printer --kiosk --kiosk-printing http://localhost:8069/``
