The printer keeps printing garbled things is caused by not closing the queuing task, and the solution is:

1. Find "Computer" on the computer desktop, then right-click "Computer", and in the pop-up options, click "Manage".

2. On the left side of the window that opens, find "Services" under "Services and Applications".

3. After clicking the "Service" function, all services will appear in the interface on the right, find the print spooler from before, click on this service, and there will be two options on the right side of the service area: "Stop this service" and "Restart this service", click "Stop this service" here

4. After the service is closed, open the C disk of the computer, open this folder according to this directory C: Windows System32 Spool Printers, and some files will appear in the computer with the problem, and delete all of them. If you do not stop the service, the files may be automatically restored after deletion.

5. Then find the service window you just opened, click "Restart this service", and return to normal after restarting the service.

If you disconnect from the computer, turn off the printer, remove the paper, turn it on and off a few times, and return to normal, then there is no problem. The reason is that there was an error in the last received printout.

If you disconnect from the computer, after shutting down and turning on the computer many times, the paper will be like this, the machine is faulty, it is recommended to contact the official after-sales service center, and the engineer will help check and deal with it.

Changing the printer data cable to another computer for testing and continuing to print is a problem with the data cable or printer interface board. The former is replaced and the latter is sent for repair.

If it doesn't work, it is a Trojan horse or system failure in the original computer (troubleshooting, you can find a system disk to repair and install), kill the Trojan horse or reinstall the system.

If it is plugged in tightly, it is still garbled, it is recommended that you change the line and try it. 2: If it still doesn't work after changing the cable, it is recommended that you uninstall the driver and install a new one. 3: If the driver is reinstalled.

Turn the printer off, then turn it back on, and you're done.

If there is a malfunction, go to a professional store and ask, I don't understand very well.
