  • Patent number: 8994988
    Abstract: Disclosed are an image forming apparatus, a host apparatus, and a print method thereof. A method includes receiving a one touch print command from a print button provided in the image forming apparatus to print an image of at least one monitor among a plurality of monitors of a host apparatus connected to the image forming apparatus. With this configuration, high quality output products may be provided without any image distortion due to a difference in resolution upon receiving a one touch print command in the multi monitor environment.
