A paper feed control system in a printer allows two types of manual paper feed operation. In a first type of manual paper feed operation, a course manual paper feed is conducted while an electrical detent operation is conducted by a paper feed drive pulse motor. In a second type of manual paper feed operation, a fine adjustment of the paper position is carried out while the electrical detent operation is precluded. A counter system is associated with the rotation of the paper feed drive pulse motor so as to provide the electrical detent operation at preselected positions. When the second type of manual paper feed operation is completed, the counter system is reset so that the subsequent electrical detent operation is carried out with reference to the finely adjusted paper position.
