A printing head and a method for applying a correction for mounting deviation of light-emitting chips are provided. The printing head includes a plurality of light-emitting chips. Each light-emitting chip includes a plurality of primary light-emitting elements that are continuously arranged. At least one of two adjacent light-emitting chips further includes at least one spare light-emitting element continuously and linearly arranged after the primary light-emitting elements. If the two adjacent light-emitting chips are both at a target mounting position, first N light-emitting units of one of the two light-emitting chips respectively face to first N light-emitting units of the other one of the two light-emitting chips, where N≥1. Each two of the light-emitting units facing to each other form a group. One of the two light-emitting units in each of the groups is set to a light emission disabled state.
