Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. Let's start with the simplest potential fixes first. Please sign off of your computer and shut it down. Next, unplug power from the printer. Turn computer back on and sign back in. After your icons come up on the computer, please turn the printer back on and try to print something. Please let me know the results.
