摘要： Disclosed is a recording system in which an operation performed on the side of a printer unit in order to change over recording density is delayed while a recording operation is in progress. When a recording density changeover command is received during a recording operation, the density changeover is performed after the recording operation ends. A control unit which controls the printer unit is informed of the fact that the measures for changing over the recording density have been completed on the printer unit side.

摘要： A positioning apparatus for positioning a reciprocally movable member, such as a guide member for a sheet of recording paper, between a reference position and a predetermined position. The apparatus includes a detector for detecting that the movable member is in the proximity of the reference position, and a counter for counting the amount by which the movable member is shifted while the detector is detecting that the movable member is in the proximity of the reference position. A controller stores the value counted by the counter, and controls drive of the movable member when the movable member is being returned to the reference position based on the count in the counter and the stored count value. A second counter may be provided to count the amount by which the movable member is shifted from the reference position to the predetermined position.
