A printing and plotting device is used for inhibiting the driving force of a moving head and enabling the ink ejected out from a printing head to be difficultly attached on a cutting head, etc. , which includes: a guide rail extending in the lateral direction above a sheet-like medium, a first and a second heads which are supported on the guide rail and are movable in the lateral direction independently with each other; a driving device having a driving force transmitting member which extends along the guide rail and is movable in the lateral direction. After the first head is connected to the driving force transmitting member by a first connecting mechanism and the second head is separated from the driving force transmitting member, the printing or cutting process relative to the sheet-like medium is conducted while the driving force transmitting member is driven by the driving device to move the first head in the lateral direction. After the second head is connected to the driving force transmitting member by a second connecting mechanism and the first head is separated from the driving force transmitting member, the printing or cutting process relative to the sheet-like medium is conducted while the driving force transmitting member is driven by the driving device to move the second head in the lateral direction.
