Can't write to printer(disconnected?) problem

I'm not sure if this is a real problem as the printer seems to be working correctly but I am getting the "Can't write to printer(disconnected?)" popping up in the message window. It is not affecting the print in any way but is this signalling something else is wrong? I have attached a picture to show you what the message looks like.

I am using Pronterface and I have a RepRapPro Ormerod 1 (green).

Thanks

Try a different USB cable, yours may for some reason catch interferences.

It seems to have gone now. I just reset the Printer and it dissappeared. It could be that so i'll have a look.
