Supplementary explanation

  • When this API is run multiple times, the callback method specified later takes effect.
  • If nil is specified in delegate when calling this API, the registered callback method is canceled.
  • When controlling multiple printers, compare the call source Printer object and the printerObj parameter, and identify the printer that has settings complete.
  • If the setPrinterSettingEx API is executed in a non-supported printer, EPOS2_CODE_SUCCESS is stored in code, but printer settings will not be executed.
