Overview:
LiquidUI Android provides the functionality of Bluetooth Receipt Printing as compared to the print generation on SAPGUI, by pairing a Bluetooth printer to the your Android device. Hence there is no need for any wired connection between the printer and the mobile device.
Usage:
1. Turn on the Bluetooth printer and switch on the Bluetooth on your android device.
2. Pair your device with the Bluetooth printer by navigating to the Bluetooth section under Settings on your device.
3. Start the LiquidUI Android and navigate to settings - symbolically three horizontal lines to the top left corner on the "SERVER CONNECTIONS" screen.
4. Select "App Settings" and choose "Default Printer".
5. You will see the Bluetooth printer name in the list. Tap on it to select.
6. A tick mark will be placed at the front of the name indicating selection.
7. You can also Tap and hold on the name to utilize other options i.e., to clear printer selection and also to update Bluetooth Printer's device credentials within the app.
Once pairing is done you can navigate to any native SAP transaction on your SAP system to generate a Bluetooth print using the print command i.e., with the help of print button.
Advisory Notes:
1. Your Bluetooth device's line drivers should be configured or registered within your SAP system using the transaction SPAD before you can start printing.
2. Also make sure that your Bluetooth printer is only paired to one Android device at a time as few of the printers cannot remember or pair multiple devices at a time.
3. It is also better to maintain only the Bluetooth printer as paired or default in the list of paired devices section of Bluetooth settings and in the list of default printer selection within the App Settings of the LiquidUI Android.
Interesting Facts:
1. You need not make default printer selection each time you start the application.
2. Print generation can be done even at a distance of atleast 10 meters. If there is a loss of Bluetooth connectivity between the Application and the printer while generating the print, the app pops-up a dialogue box stating "loss of connectivity" and once you select OK it re-establishes connection and generates the print.
