 ### how do I get the xml for a label?
-Open the free `DYMO Label` software and design a label.  When you have designed one save it.  The file it saves is an XML document like the one below.  Simply pass that XML or (hint hint) a version of that XML that you did some string replacement on to the print function with a printer name and you are printing labels.
