PROBLEM TO BE SOLVED: To provide a thermal printer configured so that a user can recognize whether a heat storage parameter is insufficiently corrected or excessively corrected at a glance. SOLUTION: The thermal printer, which is adapted to print a mixed color of a plurality of printing primary colors Y, M and C in a printing area Ar of a recording medium Pa by heating a thermal head 2, prints a print content related to a print request in the printing area Ar; prints, based on a test print request that is one of print requests, the printing primary color Y that is a test object in a first area Ar1 within the printing area Ar at a predetermined gray level (target printing gray level 255); and also prints a mixed color of at least one printing primary color M, C other than the printing primary color Y of the test object among the plurality of printing primary colors Y, M and C in a second area Ar2 adjacent to the first area 1 in a sub-scanning direction so that a gray level (target printing gray level 128) of the printing primary color Y of the test object is smaller than the gray level (target printing gray level 255) in the first area Ar1.
