Printer won’t stop printing junk pages

[Kh2345]

printer prints entire pack of paper with:

POST/ipp/printer HTTP/1.1

content length: 186

content type: application/ipp

host: local host

I am not able to print anything and this ***bleep***just keeps printing over and over all day until it runs out of paper. Help! 

I’ve tried hard reset, uninstalling drivers and printer and nothing has worked. The firmware was updated two days ago and this started.

Not sure how your printer is connected.  I have seen many post reporting this error message when printer is connected via USB.  Switching to WIFI connection solved problem.

How did you find someone to call to help you? I have the same problem. The HP Detect my device is not working at all. I keep putting in the serial number and model # but I get nothing. This is driving me crazy. Can you share a number where you were able to get direct help?

I just got off the phone with a tech. He fixed it! There are two factory resets. One is the entire reset that came from the factory and then he did a second re set to something else but I don't remember the difference between the two.  His name was Gavin. FIND HIM. He is wonderful. He is checking on me at  3 pm tomorrow to make sure the printer is still not printing up junk pages. In addition, he is giving me 15% off a ink the next time I order for my trouble. The printer was literally printing 10 junk pages before the one page I requested and like 10 junk pages after that. He said this is a good model because the ink does not smudge, which is what I need. I am so thankful. I am a teacher and I needed this in proper working order before kids showed up next week. I was not always a fan of HP, but wow, did this guy change my mind. In addition, I got a great deal from Office Depot in Bradenton, FL.  The cheap state of FL gives us a small handout of money at the beginning of the year and all of it went to this printer because I work with kids with disabilities who need lots of verbal cues like loads of pictures of actions and directions to follow. This will be a game changer in my classroom. Local schools here have no colored printers and now I hopefully have one that works properly.

This post I found fixed the issue.  

Find the part about Resetting the Print Spooler.  Very easy instructions and it immediately solved the issue.
