A print medium comprising: a plurality of print areas that are set along a longitudinal direction on a printing surface, the longitudinal direction being a direction in which the print medium in sheet form extends and being a direction along a feed direction in which the print medium is to be fed when printing is performed, and the plurality of print areas being a plurality of areas on which printing is to be performed; and a plurality of identification markers that are intermittently printed along the longitudinal direction on the print medium, each of the plurality of identification markers including a set of leading edge information and identification information and being printed in correspondence with a single print area group, the leading edge information being information for setting a leading edge position of the print area in the feed direction, the identification information being information for identifying a type of the print medium, and the print area group being formed of a plurality of mutually adjacent print areas among the plurality of print areas; wherein the plurality of print areas of the print area group are print areas having the same length in the feed direction as each other; and an arrangement interval between leading edge positions of the plurality of identification markers is an interval, in the feed direction, that is an integral multiple of an arrangement interval between the leading edge positions of the plurality of print areas of the print area group, characterized in that the leading edge information includes: a leading edge identifier, which is an identifier that extends in a band shape along a width direction that is orthogonal to the feed direction, and a blank area, which is an area that is connected to the leading edge identifier on a downstream side in the feed direction and that has a predetermined length, and in which the identifier is not arranged, and wherein the length of the blank area in the feed direction is equal to or longer than the length of the identification information in the feed direction. a plurality of print areas that are set along a longitudinal direction on a printing surface, the longitudinal direction being a direction in which the print medium in sheet form extends and being a direction along a feed direction in which the print medium is to be fed when printing is performed, and the plurality of print areas being a plurality of areas on which printing is to be performed; and a plurality of identification markers that are intermittently printed along the longitudinal direction on the print medium, each of the plurality of identification markers including a set of leading edge information and identification information and being printed in correspondence with a single print area group, the leading edge information being information for setting a leading edge position of the print area in the feed direction, the identification information being information for identifying a type of the print medium, and the print area group being formed of a plurality of mutually adjacent print areas among the plurality of print areas; wherein the plurality of print areas of the print area group are print areas having the same length in the feed direction as each other; and an arrangement interval between leading edge positions of the plurality of identification markers is an interval, in the feed direction, that is an integral multiple of an arrangement interval between the leading edge positions of the plurality of print areas of the print area group, characterized in that the leading edge information includes: a leading edge identifier, which is an identifier that extends in a band shape along a width direction that is orthogonal to the feed direction, and a blank area, which is an area that is connected to the leading edge identifier on a downstream side in the feed direction and that has a predetermined length, and in which the identifier is not arranged, and wherein the length of the blank area in the feed direction is equal to or longer than the length of the identification information in the feed direction. a leading edge identifier, which is an identifier that extends in a band shape along a width direction that is orthogonal to the feed direction, and a blank area, which is an area that is connected to the leading edge identifier on a downstream side in the feed direction and that has a predetermined length, and in which the identifier is not arranged, and wherein the length of the blank area in the feed direction is equal to or longer than the length of the identification information in the feed direction.
