HP Recommended
Product: HP laser printer M507dn
Operating System: Microsoft Windows 11

I get trouble from my printer M507dn. When I reconnect USB cable from my laptop (win 11), the printer automaticly printed a page like that:

POST /ipp/print  HTTP  /1.1

Connection: Keep-Alive

User-Agent: Windows Internet Print Provider

Content-length: 593

Host: localhost

This error made me crazy. I tried a lot to fix it: Reinstall last update printer driver from HP website: fix Registy record; reset factory setting of printer... But this error remains. 

Pleased help me!
