To sum up the article, it could be:
A messed up USB port on your computer (you can just use a different port).
A problem with Print Spooler on Windows PCs (It shows steps to reset it).
A messed up USB cable (you’d have to find out if it’s easy to get a new cable and just switch it out).
If you have a Mac resetting the print system is an option.

Good Luck.
