macOS Tahoe: DYMO 640CB USB fix: disable printer Bluetooth

macOS Tahoe + DYMO LabelManager 640CB — USB detection improves when printer Bluetooth is disabled

On macOS Tahoe, the DYMO LabelManager Executive 640CB may be slow or inconsistent to appear in DYMO Connect Desktop.

A reliable workaround is to disable Bluetooth on the printer itself while leaving macOS Bluetooth enabled.

Printer menu path:

Menu → Settings → Usage → Bluetooth → OFF

This turns off Bluetooth only on the printer, does not affect other Bluetooth devices, and allows DYMO Connect to recognize the 640CB faster and more reliably over USB-C.

This stabilized detection immediately in my case without disabling Bluetooth system-wide.
