Hello,

Often the problem is not with the printer itself, but with other factors:

1. **Printing via USB**: It is better to print via LAN (cable). only if there is no other way should you print via WLAN/WIFI, as a poor WLAN connection can also be a source of error.

2 **PDF application**: Always test first with the original Acrobat Reader and for comparison with Sumatra PDF.

3 **Driver problem**: If it still does not work, it is probably due to the Plug&Play driver of the operating system. Under Windows, the HP UPD driver is recommended. Integration should take place via TCP/IP (not IPP or WSD). Ideally, the IP address of the printer should be reserved (fixed) beforehand in the DHCP server of the router/firewall.

Good luck!

Best regards,
Aedu
