A method for printing a recording medium with an inkjet printer that includes: a printhead; a driving means that moves and positions the recording medium and the printhead relative to each other; a heating means provided at a position opposite an ink discharge face of the printhead, and that heats the recording medium from the back side of an inked surface of the recording medium positioned opposite the ink discharge face of the printhead by the driving means; and a preliminary heating means that heats the recording medium from the back side of the inked surface before the recording medium is positioned opposite the ink discharge face of the printhead, the method comprising: heating the recording medium with the heating means and the preliminary heating means to make a surface temperature of the inked surface of the recording medium 40°C or more and 60°C or less; and printing the recording medium by causing the printhead to discharge an ink that contains a solvent, a colorant, and a binder resin, wherein the binder resin is dispersed or emulsified in the solvent, has a surface minimum filming temperature of 0°C or less, and has different minimum filming temperatures for a surface portion and an interior portion, and wherein the minimum filming temperature of the binder resin is lower in the surface portion than in the interior portion. a printhead; a driving means that moves and positions the recording medium and the printhead relative to each other; a heating means provided at a position opposite an ink discharge face of the printhead, and that heats the recording medium from the back side of an inked surface of the recording medium positioned opposite the ink discharge face of the printhead by the driving means; and a preliminary heating means that heats the recording medium from the back side of the inked surface before the recording medium is positioned opposite the ink discharge face of the printhead, the method comprising: heating the recording medium with the heating means and the preliminary heating means to make a surface temperature of the inked surface of the recording medium 40°C or more and 60°C or less; and printing the recording medium by causing the printhead to discharge an ink that contains a solvent, a colorant, and a binder resin, wherein the binder resin is dispersed or emulsified in the solvent, has a surface minimum filming temperature of 0°C or less, and has different minimum filming temperatures for a surface portion and an interior portion, and wherein the minimum filming temperature of the binder resin is lower in the surface portion than in the interior portion. heating the recording medium with the heating means and the preliminary heating means to make a surface temperature of the inked surface of the recording medium 40°C or more and 60°C or less; and printing the recording medium by causing the printhead to discharge an ink that contains a solvent, a colorant, and a binder resin, wherein the binder resin is dispersed or emulsified in the solvent, has a surface minimum filming temperature of 0°C or less, and has different minimum filming temperatures for a surface portion and an interior portion, and wherein the minimum filming temperature of the binder resin is lower in the surface portion than in the interior portion.
