Starts or cancels half-speed printing. Half-speed printing causes the printer to run at 50 percent of the normal speed. It is an effective way to reduce print noise and improve horizontal alignment. n specifies whether it is set or cancelled as follows:

n =1 or 49: Start half-speed printing

n =0 or 48: Cancel half-speed printing

The printer uses half-speed printing when the operator access door is open.
