代码:
//必须引入printer库 compile 'am.util:printer:2.1.0'ByteArrayOutputStream byteArrayOutputStream = null;PrinterWriter printerWriter = null;ArrayList data = new ArrayList<>();data.clear();/** * PrinterWriter58mm * 宽度 32 英文字符 16个中文字符 * 一行最多容纳16个汉字 32个数字 或者英文字母 或者空格 */try { printerWriter = new PrinterWriter58mm(PrinterWriter.HEIGHT_PARTING_DEFAULT, 300);
