Start woking with a thermal printer SDK. It's written for android in Java.
They didn't provide any source code, but luckly, java program itself is the source code.
And now I decide to write my own SDK.
Yeah... "Vector<Byte>"

Also, the document is shit.
Document said "bitmap" has 3 modes. They are 0, 1 and 2. But in SDK, they use mode 3, which is totally undocumented and the code is spaghetti.
Another example, you can query the model string with a command, but the document didn't say anything about the return value. I have to dig into SDK and know they are using a 32 bytes buffer and treat it like a null-terminated string with default charset, I assume it's GB2312 or GB10 something something.
