The printer may not be able to print because it has no paper or the ink cartridge has run out, or it may not be in a normal network state. You can try to restart the printer, or it may be that the connection between the computer and the printer is not normal, so you can try to reinstall the driver to solve it. The following is a detailed introduction:

1. Generally, there will be an indicator light on the control panel of the printer. You can check whether there is no paper or ink.

2. Check whether it is networked. There will be an online indicator light on the control panel. Under normal circumstances, the indicator light will always be on. If the indicator light is normal, you can turn off the printer and restart it. If it is not normal, it will turn off or flash.

3. If the connection is not normal, you can open the control panel of the computer to see if the printer has a green check mark; If the connection is abnormal, you can try to solve it by reinstalling the driver or restarting the computer.

4. Check the printer port of BIOS. Some printers do not support ECP-type print port signals, so the print port should be set to normal, ECP+EPP mode;
