A blue or green light indicates the printer is
operating correctly, while a red light indicates
an error has occurred.
When the status indicator light is blue, it is possible to receive data
using both the Bluetooth and USB interfaces. However, once a
connection is established using one of the interfaces, data cannot
be received using the other interface until printing is complete.
