Android网络打印机的那些事

最近做项目有碰到使用Android手机连接网络打印机打印小票，把研究了好几天东西记录分享下。

基于环境
测试网络打印机爱普生(Epson)，测试手机华为Meta9,P9,Meta8。

• 打印一维码，我这边测试不行，有大神知道可以告诉我，可以使用zxing生成一维码二维码，在转图片，反正我用的是这种方式
• 打印二维码OK
• 文本打印完要记得多带几个回车在切纸

连接网络打印机

    /*** 网络打印机 打开网络打印机* 端口都是9100* @param ipaddress* @param netport* @return*/public boolean connction(String ipaddress, int netport){try{Socket socket;if (socket!=null){socket.close();}SocketAddress ipe = new InetSocketAddress(ipaddress,9100);socket = new Socket();  //Socket(ipaddress, netport,true);socket.connect(ipe);socket.setSoTimeout(1500);}catch(Exception e){e.printStackTrace();}}
