title: Zebra LP2844 stopped responding to ZPL Commands or Files
body: <p>I sent a couple zpl files to the printer to test it and it worked fine. </p>
  
  <p>After that I was receiving base64 encoded zpl data from UPS and creating a file and sending it to the printer via a Java applet, and now any zpl commands or files I send to it are doing nothing.</p>
  
  <p>I put it in diagnostic dump mode, sent some commands, then hit feed and it just printed a list of the commands it was sent.. so they're going through at least, but it won't print them.</p>
  
  <p>It prints other data fine, for instance when sending an image to it.</p>
