All print jobs include a message about Content-Length and Content-Type

[CosmicSheep]

Every print job prints an extra page with the following:

Content-length: 181

Content-Type: application/ipp

HOST: localhost

[also a line with character set attributes with some special characters]

---

I don't think this is a driver problem because: it happens even when printing configuration pages directly from the printer menu, also it doesn't matter which computer I print from, the same thing happens on both windows 10 (fresh driver install from HP download) and a macbook pro with Monterey.

Please advise!

Hi @CosmicSheep,

Welcome to the HP Support Community.

Thank you for posting your query, I will be glad to assist you.

I see that you are facing an issue with your Printer that prints unwanted text.

A) Please follow the steps below to perform a power drain.

1) Take out the cartridges

2) Unplug the power cord from the printer & wall.

3) Press and hold the power button down for 15 seconds and release the power button, wait for about 30 seconds.

4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.

5) Insert the cartridges back into the printer.

Remove the cartridges > Unplug the power cord > Wait for 30 seconds > Plug the power cord back in > Insert the cartridges

B) Kindly refer to the steps on this link to update the printer firmware and let me know if that resolves the issue.

C) If the issue still persists, uninstall the printer software by following the steps from this link and restart the devices.

D)  Install the printer software by clicking on the link again and let me know if that resolves the issue.

Note: Enable Bluetooth for an HP Smart app setup: Enable Bluetooth on your computer or mobile device so that HP Smart can detect the printer during the setup.
