How to print any texts or receipt to Thermal Printer on Thermal Paper

Here I’m using text variable mentioned below to print text to Thermal Printer on Thermal Paper.

String text= “Welcome to My Website\n This is a test Print”;

mmOutputStream.write(INIT);

mmOutputStream.write(SELECT_FONT_B);

mmOutputStream.write(SET_EMPHASIZED_MODE_ON);

mmOutputStream.write(text.getBytes());

Now for underline the text, these following commands should be used—

mmOutputStream.write(INIT);

mmOutputStream.write(SELECT_FONT_B);

mmOutputStream.write(SET_EMPHASIZED_MODE_ON);

mmOutputStream.write(SET_UNDERLINE_MODE_ON_1DOT_WIDTH);

mmOutputStream.write(text.getBytes());

For Line Spacing you can also use these following commands—

public static byte[] SET_LINE_SPACING_24 = {0x1B, 0x33, 24};

public static byte[] SET_LINE_SPACING_30 = {0x1B, 0x33, 30};

mmOutputStream.write(SET_LINE_SPACING_24);
