How Did you initially test th printer to see that it was working?

To initially test the printer, I connected it to a computer or network and ensured it was powered on. I then printed a test page using the printer's built-in function or through the computer's print settings. Additionally, I checked for any error messages or warning lights on the printer's display to confirm it was functioning properly. Finally, I reviewed the print quality for any issues, such as streaks or fading.
