Thanks. I will try

:-? I think we need change paper size

You're welcome my bro

I will try my dear :D Thank you for your idea

I will try to research. I used to have a device for test, now i don't. So i need find device :(

@@eddydn71 Okay. Thanks for your cooperative approach. I will also share here if I find out a solution.

Yes, but we need something like WebAPI to easy handle it

You can publish API from Python and use android like a client :D

so will i control arduino using android as client by publish Python API?

also thank you for given link of all image stream docs

I just tell my friend test for me :( Because i don't have device

@@eddydn71 Thanks, it worked for me automatically.

Maybe it can't connect to your drive, try with other device

I will try to create this series soon , thank you for your idea my bro

:) Dear, AndroidX and Android is just difference package name, other features is same :) Doesn't matter!

You're welcome, my bro :D

Printing object is null ! Have you init it in Application.java like tutorial ?

@@eddydn71 yeah I have initialized it in application.java, But in the activity we are not initializing the printing variable, we always check whether it's not equal to null. Is that the right way?

@@eddydn71 can you tell me whats the differecne between printing.print(printables); Printooth.INSTANCE.printer().print(printables); this two print functions?

@@eddydn71 We are initialing Printooth in app.java right? Not printing.

I will check soon my bro, sorry :)

I've show my device in my tutorial , please check

Yes my dear :D I think so :D Sorry i can't test all device :D
