Hi
Without you specifying your problem in more detail, we cannot help here. We need more information. Is there an error, and if so, which one? That would be a good start. Then it would be good to know which
JTL POS version is in use. Which Epson printer is being used and what firmware does it have. Is the TSE module - I deduce this from the title of the post - in the printer? Possibly the TSE signature has expired, there were countless Epson TSE units last year where the certificate expired.
