Label Printing Feature for Sunmi Pro 2 & Sunmi V2s

[rithvicheth-chan-bronxtechnology]

Dear owner,

I would like to request for distribution the feature for Label Printing Feature for Sunmi Pro 2 & Sunmi V2s, due to I have these 2 devices for testing for this implementation. So far so good, this package has helped and supported my personal and commercial project for Receipt Printing. Plus, this is my very first time to request for contributing to community.

Thanks!

Did you try the v4?
We have tl component to print via sdk

I have checked the provided docs, but could not find any guides or instructions for implementing and testing with tl component to print via sdk.

https://github.com/brasizza/sunmi_printer/blob/version-4.0/example/lib/main.dart
await printerController.printTSPL(data: tspl);

i dont have this kind of printer here, so i didnt test, but i implemented as the sdk show

Here, I have tested and log the input at Printer Controller on printTSPL function. I have tested on Sunmi V2s model. It was only the input from the action but there was not any output print label to machine and I did not received any error throw when I tried wrap the printTSPL with try and catch the error.

Test Case Prep:

1. Sunmi V2s model
2. Flutter Vers: 3.27.2

[log] Hello from printTSPL
[PrinterController] Printing TSPL data: ! 0 200 200 400 1
                    TEXT 100 100 "3" "Hello, TSPL!"
                    PRINT

Yes, I have re-checked and enable once again per guides. You can checked the provided video reference as attached. This is a Sunmi V2s that I have tested.

I see now.
i think your firmware can be older to accept TSPL method and will need to try to develop the canvas receipt but will take time because i dont have this device with me.
Give me a few weeks to find something to help you, but if you can open a support in sunmi sending your serial number maybe they can help you.
