Print direct from mac OS using Laser Printer is a mix of grey and black
i am printing from a laser printer (OKI MC853) and all of a sudden the print direct from mac OS is a mix of grey and black (when printing B&W) OR sections of colour printing is half there and half not.
however when i photocopy from the same machine the print is fine.
any ideas please ?
