First of all, TSC344 is definitely not selected, because the opening angle of the flip cover is too small, so it is not convenient to wear paper, and the default is to print a piece of paper to be removed. Most jewelry labels are spacer glue, and the removal action is easy to damage the label and the print head. Secondly, how to use CP3 140 is unclear. But I know that GODEX G530 accounts for a large proportion in Shenzhen jewelry market. You can search on Taobao. I answer my conscience with 10 years of work experience. I hope it can be adopted. Thank you.
