Also, I found that the problem is on SMTP. If you disable SMTP on both the printer via the web interface and disable the SMTP of the printer driver TCP/IP Properties, the printer will never go offline. If you turn SMTP on, you will have to define the parameters in both the Printer Network Configuration matching your print driver tcp/ip configuration on SMTP. Since I don't need SMTP at home, I just disable it.

Thank you, ZeroHour!!! Got it.

Hi ZeroHour, I have the same problems like others on my new P2055DN printer. My current firmware version is V.37.12.IR6498 from the Network Summary page. Can you please email me the download link of the beta firmware also? Thanks! Ban
