HP Office Jet 250 Mobile All-in-One Printer. I did not insert a new ink cartridge right so when I then tried to copy a document, it would not copy. I opened printer and fixed the cartridge. Then tried again to copy my document. Nothing happened when I pressed copy. I pressed power button to turn off and reset. Window says "Shutting Down". However it doesn't shut down. I unplugged printer. Nothing changed. Window still says "Shutting Down" and it's been an hour. How can this be when it has no power? It's just stuck. If I plug back in, nothing changes.
