Supplementary explanation

  • When iterating a process, be sure to generate and destroy instances outside the iterated process and not iterate the process at a short interval.
    Memory releasing by the OS may affect the process of the Epson ePOS SDK, resulting in an invalid operation.
  • When the DM-D30 connected to the TM-m30/TM-m30II/TM-m50/TM-T88VI/TM-T88VI-iHUB is replaced with the DM-D70, specify EPOS2_DM_D30 in displaySeries.
