Status LED
A blue or green LED indicates the printer is oper-
ating correctly, while a red LED indicates an error
has occurred.
When the status LED is blue, it is possible to
receive data using both the Bluetooth and USB interfaces. How-
ever, once a connection is established using one of the inter-
faces, data cannot be received using the other interface until
printing is complete.
