Hello my name is Sheldon and I am Samsung  customer executive. Most users will have a Samsung printer keeps going offline problem while using the  printer at some point. Unfortunately, we do not know why our Samsung printer keeps going offline. It happens for one of these reasons. There is a problem with the connection between the Epson printer and the Computer. The printer is unable to communicate with the PCs due to hardware or software issues. An out-of-date printer driver may cause your printer to stop operating.
