The first situation is the setting of software. All restaurant cashier software can set a certain dish or a certain kind of dish to print on the designated printer. If it is found that a certain food or a certain food can't be printed on this printer, other printing is normal. First, check the printing settings of the cashier software to see if the printer is mistyped or missed.
The second case is the printer settings. For example, the IP address set by the printer is192.1.14, but the network segment of the router is 192. 168.0.X, which will cause the printer to be unable to connect to the intranet. In this case, you can check the network segment of the cash register.
As shown in the above figure, the IP segment of the cash register is 10. 168.438+0.236.
As shown in the above figure, the IP of the printer is192.168.5438+0.14. These two devices are not on the same network segment, so they cannot print.
(The next section explains how cash registers and printers in different IP network segments can communicate successfully. )
The third situation is that the printer is damaged, which will happen in the market during the operation of the restaurant. Every print head has a service life. If you find that the printer prompts a fault, or the printer keeps dripping, it is likely that the printer is damaged. There are many reasons for printer damage, such as water, cockroaches, man-made damage, gear failure, nose failure and so on. In this case, you only need to replace the network printer with the same model or IP.
The fourth is network failure. This situation is also very easy to check. If one or more printers in the kitchen can't print at the same time, it is likely that there is a fault in the line from the cash register to the router (the crystal head or the network cable is faulty). In this case, contact the network personnel, who have professional network testers to quickly test where the fault is. Or the line from the cash register to the router (or switch) is normal. But a printer in the kitchen doesn't print, which is similar to the above situation. It is likely that there is something wrong with the line from the printer to the router (or switch) (there is something wrong with the crystal head or the network cable). As shown in the figure below:
Fifth, it is common in the network situation in recent years. The cash register and printer are not in the same network (or network equipment). Now most optical cats have routing and WIFI functions. During the installation process, the merchant is likely to connect the cashier network to the light cat, so that you can surf the Internet normally. But the printer in the kitchen is connected to another router. As a result, the cash register and the kitchen printer are not in the same network and cannot print. In this case, you can print out the original IP of the printer first. Generally, turn off the printer first, then press and hold the printing paper key, turn it on, and release the printing paper key after five seconds. This test paper will be printed, and the place marked on it is the IP address of the printer.
At this time, open the command terminal on the cash register,
Input: ping the IP of the printer, similar to: ping192.168.1.14:
If there is no access, it means that the cash register and printer are not in the same network.
The above are the causes and troubleshooting methods of most failures from the cash register to the printer. If something goes wrong during the operation, you can trust me privately.
