DCP-195C will scan and copy but will not accept material from the computer to print. Only recently had this problem. Any help please would be appreciated. (Sounds as though printing but spits out clean unused pages!! )

Have you tried unplugging the printer from the back, leaving it for about 30 seconds, then replugging it? If that doesn't work, reset to default settings on the printer. That's all I have. ;-/
