What if the small ticket machine in the supermarket is repaired and always printed?
1. We consider the problem of the printer driver. The model is wrong, or the driver is incompatible. We first determine the printer model, go to the official website or find the original drive CD to install.
2. For printer interface setting, first determine what interface the printer is. Generally, there are serial port, parallel port and USB port, which are the so-called com, LPT and USB interfaces. The corresponding printer port should be selected for the printer.
3. Sometimes we set editing or header and footer settings in the printer's page settings, which also affect the length of the printer paper. This can be seen in the browser print setting interface.
4. We consider the small ticket printer itself. We can change to another computer with different configurations to try it. If it still doesn't work, it may be different from the small ticket.
5. The power supply of the computer interface is insufficient, which mostly appears in the USB interface printer. There are many computer peripheral devices, such as camera, keyboard, mouse, USB audio and microphone, and the power supply of the computer is not large enough.
How to print garbled code on the small ticket machine in the supermarket?
① If you print correctly at ordinary times, and suddenly there is garbled code in printing, first check whether the data line contact is intact, and then pull it out and insert it again.
② After checking, the code is still garbled. Usually the data cable is damaged. There is no way to spend money to buy another one.
③ In another case, the printer driver is damaged. The solution is to reinstall the driver. Click [printer icon], press Delete or right-click the mouse, and select [delete] in the shortcut menu. You will be prompted whether to delete it. Select [yes] to delete the printer, and then reinstall it.
What about the slow printing of supermarket ticket machine?
1、 First, turn off the printer power, press and hold the printer paper output key, turn on the printer power, release the printer paper output key after about two or three seconds, wait for the test page to be printed, and observe the paper running of the test page. If the paper running of the test page is also slow, it should be related to the print head.
2、 If the test page runs normally and the light printing is slow, it is necessary to consider the problem of the printer line or the settings of the software and driver.
If the paper output is normal, that is, it is output line by line during printing, you need to see whether the printer drives printing or port printing. If it drives printing, reinstall the printer driver and try again. Then use the driver printer to test the page to see if it is slow.
