Supplementary explanation

  • When this API is run multiple times, the listener method specified later takes effect.
  • If null is specified in listener when calling this API, the registered listener 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, CODE_SUCCESS is stored in the code, but printer settings will not be executed.
