Abstract: Print heads (21-24) for printing print information in respective colors are associated with respective memories (25-28) having addresses corresponding to periods for which the print heads operate in one scanning cycle, and respective enable signal generators (29-32) for generating respective enable signals. Control information indicative of enable periods in which to print respective items of print information stored in the memories (77) is written in the enable signal generators. When the memories are accessed, the stored items of print information are read therefrom and supplied to the respective print heads, and the enable signal generators are energized to supply respective enable signals to the print heads for actuating the print heads only while the enable signals are of a high potential.

Abstract: A printing apparatus for printing the content information contained in the digital broadcast received by an STB, in which flexible printing is achieved efficiently at a low cost. The digital broadcast is received by an STB 30 and demonstrated on a display device (31) as the contents information comprehended in the digital data broadcast is printed by a printer (32). The contents information comprehended in the digital broadcast is converted by a contents information conversion unit (68) into contents suited for printing.

Abstract: In an ink jet printer and a head unit of the same, a plurality of printer heads having N-pieces of nozzles respectively, which are arranged in a sub-scanning direction at K-picture element intervals in predetermined resolution so that K/N has a value of irreducible fraction, are provided so that the nozzles face in a main scanning direction in accordance with the color of ink to be ejected, and stagger from one another by L-picture elements in the sub-scanning direction. Therefore, during one scanning operation in the main scanning direction of the printer heads, only one color of ink is recorded (deposited) on the same line on a member to be recorded. This can prevent a second color ink from being recorded before the first color ink has been dried, and enables a picture of a high quality to be printed. When the printer heads are arranged so as to be staggered in a stepped manner by L-picture elements in which L

Abstract: An ink jet printer apparatus includes a print head (65) and a color correction processor. The print head is scanned relatively to a recording medium in a main scan direction and a perpendicular auxiliary scan direction. The print head comprises M recording heads (66-69) arranged in the main scan direction while displaced from one another by L dots in the auxiliary scan direction, and each having N color recording elements. In an interleave operation, the M recording heads are fed in the auxiliary scan direction by P dots, then scanned in the main direction. This cycle is performed (K-1) times. The next one auxiliary feeding operation is by an interval of S dots. P/K is an irreducible fraction, P is an integer smaller than N•K/(K-1) and S is set to äK•Nü-äP(K-1)ü, and when M>1, for M≤K and L•M≤K, L is set to a positive integer. Alternatively, when M≤K and L•M> K, L is set to a positive integer so that L/K is equal to an irreducible fraction. The color correction processor supplies print data to the print head. The color correction processor performs color correction processing, suitable for the recording order of the color recording elements, on image signals to be recorded.
