  • Recording control device, recording apparatus, method of controlling recording apparatus, and recording medium
    Patent number: 8804183
    Abstract: A recording control device controls a recording mechanism section which performs recording on a recording medium by a recording head. An image expansion section expands data input from the outside to create image data for recording. An image buffer memory temporarily stores the image data created by the image expansion section. A recording control section reads the image data stored in the image buffer memory, and controls the recording mechanism section to record the read image data on the recording medium by the recording head. The recording control section controls a recording speed of the recording mechanism section on the basis of a creation speed of the image data in the image expansion section.
