本発明のプリンタにとって好ましい。In FIG. 1, a recording medium 1 such as paper or a plastic sheet is supported by a conveyance roller 2.3 consisting of a pair of rollers arranged above and below, and is supported in the direction of arrow A (
(sub-scanning direction). A guide shaft 4 is provided in front of and parallel to the conveyance roller 3, and a carriage 5 reciprocates along the guide shaft 4 in the direction of arrow B (main scanning direction). A recording head 6 is mounted on the carriage 5. The recording head 6 consists of multiple sets of heads that can be driven independently, and in this embodiment, as shown in FIG. 2, there are heads 61 to 63 for black ink printing, 64 for yellow ink printing, and magenta ink printing. Four sets of nozzle arrays, 65 and 66 for cyan ink printing, are arranged in the main scanning direction. This nozzle row has nozzle openings formed in the sub-scanning direction, with n numbers 61 to 63 each for black ink printing and m numbers 64 to 66 each for color printing. As shown in FIG. 4, an electrothermal converter 11 is provided as ink discharge control means. By driving this electrothermal transducer 40 based on print data, flying ink droplets are formed, and recording is performed while making them adhere to the recording medium 1 as print dots in a predetermined pattern. In this way, an electrothermal converter was used in this example, but in this case,
Compared to piezoelectric transducers, multi-nozzle formation is easily achieved.
Preferred for the printer of the present invention.

In the case of this embodiment, the detector 31 detects a printing mode such as a black and white printing mode or a color printing mode and sends a detection signal 36.
is output to the control unit 32, and the control unit 32 has previously loaded image information 35 obtained from an image reading device such as a CCD into the line memory 34, and when receiving the detection signal 36, it outputs the image information 35 obtained from an image reading device such as a CCD to the line memory 34. Nozzle selection control signal 37 for instructing the nozzle
A printing speed control signal 39 instructing the scanning speed corresponding to the nozzle is outputted to the printing drive unit 33, and a line memory read control signal 38 corresponding to the printing speed control signal 39 is outputted to the line memory 34 to read the line. Print information is sequentially read from the memory 34 to the print drive section 33 to drive the recording head 6, and prints while scanning in the main scanning direction at a constant speed.

印字動作を行なう。Here, the recording head 6 is capable of printing 16 dots per 1 mm, and black ink printing nozzle arrays 61 to 63
The number of nozzles n is 256, and the nozzle row for color ink printing is 6.
The number m of nozzles from 4 to 66 is 128. When a 24V, 10μ5ec(7) pulse voltage is applied to the electrothermal converter 11 at a frequency of H2(7), the above-mentioned print control section first controls the nozzle array for black ink printing in the black and white printing mode. The nozzle selection control signal 37 is sent so that only nozzles 61 to 63 print, and the print speed control signal 39 is sent to print at three times the speed of the color printing mode because there are three nozzle rows 61 to 63. Output. At this time,
The nozzle selection control signal 37 indicates that the ink droplets are i in the main scanning direction.
Ink ejection control is performed at appropriate timing according to the interval between each nozzle row on the recording head 6 so that 16 dots are formed per n+m. In the case of color printing mode, nozzle rows 64 to 66 for color ink printing, and furthermore, nozzle row 6 for black ink printing when using black ink.
Auxiliary conversion to image information 35 using 128 nozzles of 3,
The image is subjected to image processing such as masking and (gamma) correction and stored in the line memory 34, and then the same printing operation as in the monochrome printing mode is performed.

間で1枚のフルカラープリントが得られた。In this embodiment, when the main scanning speed of the recording head 6 is set to 528 mm/see in the black and white printing mode, and printing is performed in the forward and backward passes of the main scan, the A4 size recording paper can be fed horizontally at 43 mm/see in 1 minute. You will get several black and white prints,
Also, in color printing mode, the speed is 187.5mm/s as well.
By setting ec and printing on the forward pass of the main scan, one full color print was obtained in 1.5 minutes.
