A printing apparatus includes an obtaining section that obtains encoded data in which compression is performed, a decoding section that decodes encoded data to obtain image data for printing, and a printing section that performs printing by using image data for printing. The encoded data is encoded data including, for a respective one of the blocks, first compressed data in which quantized values obtained by performing orthogonal transformation for a respective one of N color components are each compressed, and second compressed data in which, by using a dictionary in which a plurality of different colors are registered as indexes, a corresponding one of the indexes associated with the color of each pixel is compressed. The decoding section decodes the first compressed data in N cycles and decodes the second compressed data in one cycle to obtain print data decoded in units of the blocks.
