Why is my printer not showing up on my Mac desktop?

If your Mac shows printer states "Offline" or not display in "Printers&Scanners", it means that Mac did not recognize the printer.

● Please try to unplug and plug the USB cable on the Mac computer and printer sides.
● Then restart the printer (power off then on).

If it is still not displayed in "Printers&Scanners", we need to check the USB connection.

● Connect your own flash drive using the USB adapter and check whether the computer can read the data.
● Unplug the flash drive and replace it with the USB cable of the printer. Usually, if a Mac can recognize a flash drive, it means that the USB adapter provides a stable data connection for the flash drive. Similarly, the USB adapter can provide a stable data connection for a printer. If the flash drive is not recognized, it may be necessary to change the USB adapter.
