Barcode Scale / Label Scale

In a barcode printing scale, a label is printed with a barcode that encodes information about the weight or price of the item. This allows the system to identify and retrieve the item's code, weight, or price.

You can weigh an item in the scale and print a detailed label, which can be either "weight embedded" or "rate embedded," with the item's weight or price encoded directly in the barcode. LithosPOS supports weighted barcodes in EAN 13 and UPC-A formats

LithosPOS supports both barcode printing scales and integrated scales and bluetooth scales.

Barcode scale setup

When using a barcode scale, a label with a barcode is printed as the item is weighed. This barcode contains embedded information such as the item prefix, PLU code, and either the weight or price of the item. The cashier can scan this barcode to automatically add the item to the invoice

To set up a barcode scale go to Integrations in the back office and install the barcode weighing scale.

• Then go to settings in the side menu of back office and you can see the ‘Barcode Scale’ option and click on it.

• Then Select the Barcode Type, [Weight digit/Rate digit]

If you choose the ‘weight digit’ type, the last section of the barcode will represent the weight of the item. If you choose the ‘Price digit’ type, the last part of the barcode will represent the price of the item.

Barcode format in weight digit type

• Prefix: In the 'Weight digit' type barcode format, the default prefix is 9911. You can also enter your custom prefix if needed.
• Entry code Digits: Specify the required number of digits for your PLU codes (Price Look-Up codes), typically ranging from 3 to 5 digits. This code serves as a unique identification number for each weighted item, for easy scanning tracking.
• Weight Digits: Then enter the required number of digits for your item's weight, typically 5 to 6 digits. In this type the last section of barcode represents the weight of the item.
• Example: If your prefix [XXXX] is 9911, the PLU [PPP] is 234, and the item weight [WWWW] is 1000 grams, then the barcode format would be:
  [XXXXPPPWWWW] = [99112341000]

Barcode format in Rate digit type

• Prefix: In the ‘Rate digit' type barcode format, the default prefix is 9911. You can also enter your own prefix if needed.
• Entry code Digits: Specify the required number of digits for your PLU codes, typically ranging from 3 to 5 digits. This code serves as a unique identification number for each weighted item.
• Rate Digits: Then enter the required number of digits for your item's rate, typically 5 to 6 digits.
• Fractional Digits: Here you can specify the number of fractional digits to be used for the currency.
• For example: If your prefix [XXXX] is 9911, the PLU [PPP] is 234, and the item Rate [RRR] is $100, and the fractional value [FF] is .50, then the barcode format would be:
  [XXXXPPPRRRFF] = [991123410050]

Finally, enter submit to save the settings.

Syncing Data to Scale

• Push Item Price Details to Scale: To support syncing item prices with your scale, download the LithosPOS Tools app.

• Login and Navigate to Scale Settings: Log in using your credentials, then go to the Scale/Label/Barcode options.

• Add Scale Information: Add the scale name and IP address to establish a connection. Once connected, the scale's MAC address will be visible.

• Sync Data: Select the scale, click the three dots, and choose Sync Data. All items that have barcode scale support enabled in the POS will be pushed to the scale, and the item names will be updated accordingly.

Bluetooth scale setup

LithosPOS supports Bluetooth scales, but this feature is only available on Android and iOS devices, not on desktop. To connect a Bluetooth scale:

• Go to the POS screen.

• Navigate to Settings > General Settings.

• Click on Bluetooth Scale.
• Search for your scale, select it, and connect.

Next, go to the Item Settings in your back office:

• Find the items you want to weigh using the Bluetooth scale.
• Open the item settings and enable the Weight Item toggle.

IMIN Scale & SUNMI scale set up

If you have an IMIN or SUNMI scale, it can be easily connected to LithosPOS:

• Go to POS Settings.

• In General Settings, find the IMIN/SUNMI scale option and connect it.

• Next, in the back office: Enable the Weight Item toggle for each item that requires weighing.

• When you add a weighable item to the cart, a pop-up will appear, automatically filling in the weight from the scale. Click OK to add the item to the cart.

If your POS device has an inbuilt scale, it can be connected in the same way.
