I understand that your printer is not printing. I can help you with it. In order to help you better with this issue, please provide the answer to the following questions:
1. May I know the make and model number of the printer
2.Does the printer is connected to the computer using a USB cable or is that a wireless printer?
3. If it is a wireless printer, does the wireless signal is showing on the printer display?
4. If it is wired printer, have you tried connecting the printer to different USB ports of your computer?
Once I get the answers, I will start the troubleshooting.
Thank you. Have a great day!!!
