In order to enable Epson API logging for the TM-S2000/9000 you must enable logging through an INI file. Please locate "LogSettings.ini" in the following location:
C:\Program Files\EPSON\TMSDriver\bin
(If both 32 bit/64 bit are in a 64 bit OS, the 64 bit version is stored in the x64bin folder.)
Modify the option "LogEnabled" to 1 to enable API log output. Be sure to save the LogSettings.ini file after modification to ensure the option is set.
Once logging is enable you can find the log file "TMS2000API_MM-DD-YYYY_XX.log" in the following location:
%ALLUSERSPROFILE%\EPSON\TMSDriver\Trace
