Content Length, content Type, and Host information won't stop printing at the top of every page

[Balvich]

I recently got a new windows 11 desktop computer and re-installed my printer to the new computer and every time I print a page the Content length, content type, and Host information won't stop printing at the top of every page I print. How do I get that to stop printing?

Had a similar issue today. On a MFP m183fw


My fix was the following:
Download and install firmware for the printer.
Download and install PCL6 drivers for the printer
Select the new driver in the advanced printer properties for the printer located at:
Printers & Scanners -> (Printername) -> Administrate -> Printerproperties -> Advanced 

Choose the new PCL 6 driver and select apply, print a test page to see if it works.
