Supplementary explanation

  • This API is not executed on the main thread. Execute it on the sub-thread.
  • When connected to the printer with Bluetooth, executing this API while a slip sheet is inserted by readMicrData causes the slip sheet to be ejected.
  • Executing this API while waiting for paper insertion after executing waitInsertion, readMicrData, and cleanMicrReader cancels waiting for paper insertion.
    At that time, processing result of waitInsertion, readMicrData, and cleanMicrReader is not notified.
  • If disconnect is conducted during an application background transition event process, wait until disconnect completes.
  • When using multi-threading to connect to multiple printers or peripheral devices, this API and connect cannot be started for other printers or peripheral devices until this API finishes processing. Start the next process after this API finishes processing.
