Claim:
A printer comprising: supporting means for supporting a recording medium, which is adapted to record data and which has a predetermined print thereon that is pre-printed by a manufacturer of the recording medium, the supporting means including a setting area at which the recording medium supported by the supporting means is set, and the supporting means being movable between a print position at which printing on the recording medium set at the setting area is possible and a setting/removing position at which the recording medium is settable on and removable from the supporting means; printing means for printing in a printing area on the recording medium set in the setting area of the supporting means when the supporting means is at the print position; an aligning member movable between an aligning position at which the aligning member partially overlaps with the setting area, and does not overlap at least with the printing area of the printing means, and a retracted position to which the aligning member is retracted from the setting area; wherein the aligning member comprises an indicator as a reference of a position and a direction of the printing area of the printing means, and when the aligning member is at the aligning position, the indicator is adapted to be aligned with the predetermined print on the recording medium so as to align a desired area to be printed on the recording medium with the position and direction of the printing area of the printing means; and wherein the aligning member moves with respect to the supporting means from the aligning position to the retracted position when the supporting means moves from the print position to the setting/removing position, and the aligning member is movable from the retracted position to the aligning position when the supporting means is positioned at the settable/removable position.
