Convert Epson PrintCD files to Casio - is it possible?

I have a new question for this thread: Let’s say I have some .ec3 files, would I be able to change those to another format, then buy a $90 casio thermal printer to replace my r200/220?
Also, which printer would be best? Casio CW-100, CW-75, CW-L300, or even a Primera Signature Z1? I’m looking for ease of use, high quality and inexpensive ribbon.

No, I think we’ll have a new thread for this unrelated question. Please don’t hijack threads in future.
