Error: Thermal label output

If you receive an error that says it's unable to close the interface and device it's likely due to a mis-matched power adapter on your LP2844 printer. Be sure to use a Hitek Power adapter, Model # PLUS120 with 20V, 2.5A output.

While we highly recommend replacing the printer with a current model like the Zebra ZP450, you can purchase new adapters from the Zebra UPS (Power Supply, 100-240V, IEC320C5) website.

See attachment below for a reference photo of this power adapter.
