More than HP printer models vulnerable to two very critical vulnerabilities
Over a hundred HP inkjet printers are vulnerable to remote code execution vulnerabilities that are classified by HP as critical. By exploiting the vulnerabilities, an attacker could remotely execute arbitrary code by sending a specially prepared file.
There are two vulnerabilities that are both classified with a severity of 9.8 out of 10. By sending a maliciously crafted file to a vulnerable device, attackers can trigger a buffer overflow and then remotely execute arbitrary code repors myce today. HP has made firmware updates available. Owners of HP PageWide Pro, DesignJet, OfficeJet, Deskjet and Envy series printers should check this page to see if their exact model is affected. They should then download firmware updates that patch the vulnerabilities from the HP website.
HP urges users to install the updates as soon as possible, as the company writes, ” The information in this security bulletin should be acted upon as soon as possible.”

I'm not sure I understand correctly but... to send a prepared file, the attacker has to be either in the printer's network, or the PC's network the printer is hooked up to. Okay, so far so good (my printer doesn't even have WLAN so it's just an USB printer, no danger here).
Then again, what does that really mean? What could they do with a hacked printer? Not print my files?
In the case of wifi printers, perhaps get remotely view what it just printed.

Hacking someones printer to spam dickbutts until they run out of paper could be pretty hilarious.

like printer processor have high computing power to do "things"
in the first place its output-device anyway, so even it hacked what it can do will be really limited
