Supplementary explanation
- This API is not executed on the main thread. Execute it on the sub-thread.
- When communication with the printer is no longer necessary, be sure to call disconnect to terminate it.
- When operating with multiple printers connected in a multi-threaded manner, this API and disconnect cannot be executed on other printers until this API has been processed. Please wait for this API to finish before executing it.
- The printer status is returned to the event registered with the LFCPrinter class.
- If you are using DHCP to assign the IP address of the printer, specify the MAC address of the printer as the identifier.
- Devices other than printers are exclusively locked.
- While connecting to a single printer using the LFCPrinter class, do not use classes other than Log class and Discovery class for the same printer. While connecting to a single printer using a class other than Log class and Discovery class, do not use LFCPrinter class for the same printer.
