In the parallel port detection mode, the bluetooth terminal device 500 completely forwards the received detection data to the printer 600 without performing operations such as protocol analysis, so that whether the parallel port of the bluetooth terminal device works normally can be detected by checking whether the printing data of the printer 600 is consistent with the detection data sent by the upper computer 400.
After the bluetooth terminal device 500 is powered on, the bluetooth terminal device defaults to be in a normal working mode, after receiving data, the bluetooth terminal device firstly judges the current working mode, and if the current working mode is the normal working mode, corresponding processing is performed according to the command words obtained by analysis, such as checking whether the data is legal, whether the data needs to be printed, whether the working mode needs to be changed, and the like.
