An ink jet recording apparatus, which records a image on a recording medium using a recording head provided with a plurality of ink discharge ports, comprises a rotative platen having a plurality of supporting pieces arranged at predetermined intervals; rotation means for rotating the platen; conveyance means for conveying the recording medium; control means for controlling the rotation means to rotate the platen in the conveying direction of the recording medium in synchronism with the conveyance of the recording medium when recording is performed near the edge of the recording medium conveyed by the conveyance means. With the structure thus arrange, this ink jet recording apparatus is capable of performing the entire area recording (no margin recording) on a recording medium without staining the platen that supports the recording medium at the time of recording.

Ink jet recording apparatus and recording method therefor

To simplify the management of unique information on printing apparatuses, the printing apparatus sends the HS data unique to a particular print head to the computer terminal equipment which, based on the HS data, corrects the print data and sends the corrected print data to the printing apparatus.

Print system and print method

An ink jet recording apparatus, which records a image on a recording medium using a recording head provided with a plurality of ink discharge ports, includes a rotative platen having a plurality of supporting pieces arranged at predetermined intervals; a rotation unit for rotating the platen; a conveyance units for conveying the recording medium; a control unit for controlling the rotation unit to rotate the platen in the conveying direction of the recording medium in synchronism with the conveyance of the recording medium when recording is performed near the edge of the recording medium conveyed by the conveyance unit. With the structure thus arranged, this ink jet recording apparatus is capable of performing the entire area recording (no margin recording) on a recording medium without staining the platen that supports the recording medium at the time of recording.

A printing method and apparatus in which basic image data and information of the printing position of the image data on a recording medium are input from a data source and stored in advance, and the designated image data is bitmapped at the printing position to print an image, thereby increasing the printing speed, and a printing system including the printing apparatus. In this system, image data sent from a host is registered as a basic image, and the image is bitmapped in an image memory on the basis of the information of the printing position, of the stored basic image data on a printing paper sheet, sent from the host. The image data bitmapped in the image memory is then output to a printhead to print the image. When the bitmapped image data is to be copied to a print buffer on the basis of an image copy command, the copy operation is preferably performed concurrently with registering operation for an image management table and bitmapping operation for an image registration buffer which are performed when image data different from the image data to be copied is input. In addition, the registered image data may be stored in one print buffer, and the registered image data may be copied to another print buffer on the basis of another command. Printout operation may be performed on the basis of the copied image data.

Printing method and apparatus and printing system including printing apparatus

An ink-jet printing apparatus receives image data from a host computer and prints the image data. If an elapsed time from an end of printing processing for one printing job to start of printing processing for the next job is less than a predetermined time period, printing processing for the next job is started, without subjecting ink-jet heads to a recovery process, following the end of printing processing for the one job. The recovery process is carried out not only when the predetermined period elapses but also whenever processing for printing on a predetermined amount of printing medium is executed.
