You might want to update the firmware on your HP laser printer, pronto.
HP published a security update on its website confirming that there are three separate security flaws affecting several models of laser printers. According to HP, certain LaserJet printers “may potentially be vulnerable to Remote Code Execution and Elevation of Privilege when processing a PostScript print job.” The company didn’t reveal any other details, but that certainly sounds bad. Fortunately, there are firmware updates for affected printers that you can download to resolve the issue.
The three security vulnerabilities affect different models, which are listed on the security update page. There are simply too many to list here, so you should probably look at the list to see if your printer is affected. If it’s any consolation, they mostly appear to be enterprise-grade printers.

HP rated the security flaws by severity, with one of them coming in as Critical, one as High, and the last one as Medium. In other words, anyone who owns one of these printers should prioritize getting the new firmware installed ASAP.
It would probably be kind of embarrassing if you were seriously compromised by a printer, so don’t let that happen.
