Sounds like a hardware issue here. Check your power cable if it is secured to the printer. Maybe your printer has had it's time and it's probably better getting a new one with warranty.

Hello Lulian,Provided you have the correct software and driver/firmware update then the ONLY thing that can cause this is the RAM buffer.Yes I know that software on Win 7 can sometimes "loose" the odd icon, but with the printer problem you have I know its not that.What is going on is that the on-board memory is buffering everything to the printer. What this means is that you can stop it at the printer (as its all there) but the software on the PC (IF its up to date) cannot do anything as all its been doing is spooling the file to the printer.If you can....you could look through the printer booklet and see if there is a way to switch off the buffer which would then mean that the print job would be spooled to the printer via the PC bit by bit and the software would be able to stop it.But before you do all that.... just go and manually look for the firmware and software upgrade and then see if that solves it.Hope that helps you and if so please rate me.Regards
