I have a LaserJet Pro 400 M401n connected to a PC running Windows 7. It has worked great for months, but earlier this week I turned on the computer & found that I couldn't print.
The printer appears in the Devices & Printers window, but it's greyed out. If I remove it & reinstall it it becomes available & works great all day. However, if I shut the computer down or reboot it the printer goes back offline. I've tried plugging it into a different USB port but it didn't solve the problem. Also, for some reason I can't delete, or configure, the port in the printer settings, or add a new port for that matter. I get error messages saying either "selected port cannot be deleted. The request is not supported" or "An error occured during port cofiguration. This operation is not supported.
I'm really stumped on this one.. Does anyone have any ideas?

Sorry to hear about your issues, one thing that you may just want to do anyway is check if newer firmware is availible.
Additionally for this issue it may be related to a service that may have crashed, that makes sure the device always is a printer as this device has "Smart Install" which allows printer to come up as a Mass storage unit with the software availible. If you go to the Settings > Service > HP Smart Install > select Off.
Let me know if that helps fix this issue.

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at: http://h30499.www3.hp.com/t5/Printing-and-Digital-
I hope this helps!
