The technique of the present invention allocates a coordinate point of target image data on a color space to multiple lattice points in a color conversion table and reads data stored at the multiple lattice points. This arrangement ensures high-speed color conversion of the target image data. The procedure selects multiple lattice points and allocates a coordinate point of one target image data to the selected multiple lattice points. The procedure then specifies color-converted image data corresponding to the target image data, based on data read from the multiple lattice points. A first application allocates the target image data to the coordinate points of the multiple lattice points arbitrarily selected in the vicinity of the target image data. A second application allocates N-dimensional target image data to the coordinate points of multiple but not greater than N lattice points. A third application calculates an arithmetic mean of the data read from the multiple lattice points to specify the color-converted image data. Any of these arrangement effectively enhances the conversion accuracy without increasing the size of the color conversion table.

The pulse generation circuit generates a first pulse signal and a complementary second pulse signal. The first and second pulse signals are activated simultaneously in a normal mode and activated selectively in response to a test input signal in a test mode. A multiplexing input circuit selects and outputs one of a data input signal and a test input signal as a latch input signal in response to the first pulse signal and the second pulse signal. The latch input signal corresponds to the data input signal in the normal mode and corresponds to the test input signal in the test mode. The latching circuit latches the latch input signal to generate data output signal. The length of data transfer path is reduced, and DtoQ delay can be decreased.

When a host computer makes a printer print a document, the driver on the host computer sends character codes of characters that appear for the first time in that document and corresponding character images to the printer in advance, and registers them. After this process, the driver transmits, to the printer, characters in the document to be printed as character codes, and data other than characters as mapped image. The printer maps an image on a page memory, maps characters as images with reference to the registered character codes and character image, and superposes the mapped character images on the image mapped on the page buffer. The printer prints the image on paper. The printer can divide an image into bands, and can map the image in units of bands, in place of pages. With this arrangement, the memory capacity can be reduced, and bands having identical contents or blank bands can be processed as codes.
