Even the Kroy website is a little light on the TM600 info. The closest was some FAQs (
http://www.kroy.com/techsup/600faq.htm). I have a K3100 which comes with some basic lable design software, which it appears you can download from Kroy, but it doesn't look compatible with the TM600. For what it's worth, the K3100 was a great investment.
