    摘要: Data processing method and apparatus for converting data such as character data or image data of a resolution X into data of a resolution Y which are effective for use in, particularly, a recording apparatus such as an ink jet printer or the like. The data processing method comprises a first dividing step of dividing the data of the resolution X in the main-scan direction every A bits; a first converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a first conversion pattern table; a second dividing step of dividing the data which was obtained by repeating the conversion by the first converting step by a number of times as many as a plurality of lines in the sub-scan direction every A bits; a second converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a second conversion pattern table; and a reducing step of reducing the data of the resolution Y obtained by the second converting step by a thinning process by using a third conversion pattern table.

    摘要: A replaceable ink cartridge, usable with a bubble jet printer, includes a container having front, back, top bottom and side walls, the container being divided internally into a first chamber and a second chamber having a common partition extending downward perpendicularly toward the bottom wall to provide an opening between the chambers formed by the partition proximate to the bottom wall. The first chamber contains a reservoir of liquid ink and is generally sealed from ambient air except through the opening, and the second chamber has an air vent for admitting ambient air into the second chamber and an ink supply outlet in the front wall. The second chamber contains a sponge-like material for retaining ink, at least one groove in the second chamber side of the partition extending from the opening and terminating at a point partly up the partition to form an air flow passage from the second chamber to the first chamber, the sponge-like material being positioned in the second chamber to permit flow of air from the air vent to the groove when the level of retained ink in the sponge-like material is proximate to the point where the groove terminates. The container is removably mountable in a printer mounting with the bottom wall facing downward and the ink supply outlet facing an ink jet print head so that the ink supply outlet is connectable to an ink port of the ink jet print head.
