Random pages printing with curl command

I need some help with this... My printer (hp inkjet) will randomly print 3 pages with just a header that includes the curl command (see photo) since this is a major waste of paper, how do I get this to stop?

I don’t have any server type apps installed so I don’t know what’s going on.

Is someone getting in to my printer or how would I know if my Mac is sending these to the printer?

Do you have a netgear router?

Look here and search for “printer”. It looks like it could be something to do with vulnerability scanning in your router.

Suggestions are:

• turn off the vulnerability scan in the router
• turn off the web services on the printer
