Embodiment 1
[0019] In this embodiment, the device with printing function is a printer.
[0020] Such as figure 1 As shown, the printing indicating device 4 set in the printer of this embodiment is a light emitting device, the light emitting device is set to a light emitting diode, a fixing frame 2 is provided outside the casing 1, a fixing rod 3 is set on the fixing frame, and a fixing rod 3 is set to be fixed. The base 5, the light emitting diode is installed on the fixed base 5. by figure 2 It can be seen that the print indicating device 4 is connected to the cash box interface 7 of the printer through the wire 6, and the cash box interface 7 is connected to the CPU 8 of the printer control unit.
[0021] The function process of this embodiment in the use process is as follows, such as image 3 , 4 As shown, when printing is required, the printer sends instructions to CPU8, and CPU8 controls the level of its output signal control pin, thereby controlling the level of the corresponding pin...
Embodiment 2
[0034] The difference between this embodiment and Embodiment 1 is that the cash drawer interface 7 of this embodiment is connected to the printing indicating device in a wireless connection, and wireless technology such as infrared technology, Bluetooth technology, radio frequency technology, etc. can be used for connection.
[0035] Such as Figure 5 As shown, this embodiment is provided with a wireless transmitting module 9 at the cash drawer interface 7. The control terminal 91 of the wireless transmitting module is connected to the second pin 72 of the cash drawer interface, and the pin 92 of the wireless transmitting module is connected to the cash drawer interface. The fourth pin 74 is connected, so that the wireless transmitting module 9 and the cash drawer interface 7 are connected.
[0036] Such asFigure 6 As shown, a wireless receiving module 10 is provided at the printing indicating device 4, and both ends of the wireless receiving module are respectively connected to t...
