Question

Hello, why does tps520 print tickets only with the demo apk? Any other application does not print anything. I tried with many pos apk and the printer is not detected.

Answer 1

Third-party applications cannot be used directly after installation. You need to develop applications based on Telpo SDK before printing. Call telpo's print interface

We have same issue. Without SDK you can't print. This makes integration very problematic!
