Push things to buffer

Thermal printer is a kind of high speed printer, so we need push all things to the buffer first.

// Push Text
// text: string            # The string you want to print
// size: number            # 0 ~ 7 Level
RNXprinter.pushText("Hello World!!!", 0);

// Push Image
// size: index             # The FLASH index of image
// Currently only supported without download image, you need use your computer to help
RNXprinter.pushFlashImage(0);

// Push Cut Paper
RNXprinter.pushCutPaper();
