RSS Feed to print through receipt printer

Processing Coding Questions
1

Hi! I’m very new to Processing and coding but I’m trying to print the content of an RSS Feed to print through a receipt/ thermal printer.

I can print text through the MyPort.Write function but it’d be great if it would print all the content without anything having to be typed in. I get the content coming up in the run window, just trying to get it to print.

Any help would be amazing!

import processing.serial.*;

Serial myPort;  // Create object from Serial class
int val;        // Data received from the serial port

void setup() {
  String portName = Serial.list()[2];
  printArray(Serial.list());
  myPort = new Serial(this, portName, 19200);
  // Send a capital A out the serial port:
  myPort.write(0x1B); 
  //ESC POS command
  myPort.write('@'); 
  //ESC POS initialize followed after command
  myPort.write("news news ahahahahahaha()"); 

  //Print "Hola Epson" to buffer
  myPort.write(0xA); 
  //Print and Line Feed from B
}

void draw() {
  XML xml;
  //String url = "http://rss.news.yahoo.com/rss/topstories";  
  //XMLElement rss = new XMLElement(this, url);
  xml = loadXML("https://www.theguardian.com/international/rss");
  XML channel = xml.getChild("channel");
  XML[] items = channel.getChildren("item");


  for (int i = 0; i < items.length; i++) {
    //int id = children[i].getInt("id");
    //String coloring = children[i].getString("species");
    //String name = items[i].getContent();
    XML title = items[i].getChild("title");
    println(i);
    text(title.getContent(), 10, i*15);
  }
}

Hi @Lili – have you looked at other thermal printer posts to see if they might be helpful, or to contact those users?
