A development device includes a developer carrier supplying developer to an electrostatic latent image carrier which is rotatable. Thus, the present invention allows the same printing region of the print medium to be sequentially printed by the respective nozzle arrays provided in the print head in accordance with image data thinned-out by the mask pattern M, thereby completing the image by multi-pass. Corresponding apparatus for effecting such methods are also provided. Such page tailoring techniques may include stretching the content across a plurality of files, discarding a portion of the content, reducing portions of the content, or the like. The ultrasound image is generated in response to manual rotation of the catheter and the ablation spark is generated only when the physician is satisfied as to the orientation of the electrode within the vessel.
