ActivityStarter and Printer POS

[Carlos Andre]

I'm developing an app that will print tickets, but I'm not sure how to do this. I think it would be through the activitystarter. Attaching printer documentation with classes and packages. can you help me? Thank you.

Unless you are comfortable with Java and want to write an extension, this doc is useless ...

A data stream doc would be more helpful.

This is all the stuff I own.

Buried deep in your zip file there is a built sample .apk file at

\20190123_SDK_TSG800 (4).zip\20190123_SDK_TSG800\TSG800 - Impressora\ESCPOS\PrintESCPOS_TSG800\app\build\intermediates\instant-run-apk\debug\

that you should be able to extract using 7zip.

What happens if you load that to your phone/device and run it?

How were you planning on connecting your phone/device to the printer?

(BlueTooth? / WiFi?  / USB Cable?)

[ABG]

There is a more likely .apk file higher up in your .zip file.

What do you get if you run it?

(See attached)

[Carlos Andre]

I performed. Is a sample application with printer features (center text, left text, bold ...)

[ABG]

Did the sample app see your printer?
