The printer is giving you an error message and there is no printing happening.

Turn off the printer by pressing the power button, then lift the lid covering the ink cartridges. A lever is inside the same area as the ink cartridges towards the back and middle of the printer. Lift this lever to remover the paper path cover. After removal, inspect the paper path for jammed pages. If paper is present, grasp it firmly with both hands and pull it towards you. If the problem is still not resolved, paper may have caught near the input tray. Turn the power off my pressing the power button. Extend the input tray out fully and slowly. Then, gently turn the printer on its side. Examine the gap where the input tray was before. Any paper in the slot should be held securely and pulled towards you. When finished, return to the printer to its proper upright state and push the input tray back to its original position.

The printer is capable of printing, but printing from the computer is met by an error message.

Update the driver by going to the manufacturer's website, then downloading and installing the correct driver based upon the printer's model and your computer's operating system (OS). The operating system can be found by going to the start icon on your computer dock (usually at the bottom left or right of your screen) and then by selecting the "about" or "settings" tab. Alternatively, if your computer provides a search bar (it can be found by clicking on the start icon), you can then enter "operating system" into the search bar and looking through the results. If your computer is a PC, generally your OS is a version of Windows (7, 10, 10 pro, vista, XP) and if your computer is a Mac, your OS is generally a version of Mac OS.
