Develop POS Android app connect to web app (firebase) to print receipt with thermal printer -- 2
Budget: $30 – $250 USD
Currently we have a web app and we are using the app Rawbt to connect with POS printer. But this solution is sometime slow.
We we would like to have an android app which can connect to our cloud firestore database and send stored receipt to POS printer (to print and cut receipt)
We will connect to printer via Wifi
Current:
1. User sign into web app and navigate to order history
2. User Click print receipt
3. A preview print screen opens and user can change printer
4. User click printer again
5. Bill printed (and full/partial cut bill if needed)
Result:
1. User sign in to web app and navigate to order history
2. User Click print receipt
3. Bill printed (and full/partial cut bill if needed)
End product should have 2 modules:
A)
1. Find printer device.
2.Connect Printer + get support print type.
3. Send command by print type.
4. Send keep alive connection paired with printer.
B)
1. Init background service when user accepted.
2. Connect and keep alive with printer device.
3.Connect to firebase service.
4. Identifies the print device on the system for threading print jobs(to step 4).
5. Init threading listen to the change of the print command.
6. Execute the print command when there is a command in the change in step 4.
7. Update jobs state when completed or error or other cases.
Can you help us?
And how long and how much will it takes?
Thank you
