Abstract: It is an object of the present invention to provide a printing apparatus and a printing method which can perform an appropriate printing operation on a print medium while keeping an ink ejection range to a minimum required even when the print medium transported is deviated from a theoretical position, and which can also reduce a running cost and ink mist. Thus, the present invention is characterized by determining the actual position of the print medium transported to the printing position; based on the determined print medium position, setting an area slightly larger than the print medium lying area as a print area; and performing the printing operation on that area.

Abstract: The invention is to provide a recording apparatus and a recording method, capable of automatically specifying a type of a recording medium by a simple and inexpensive structure, thereby automating a sheet type setting operation and avoiding an error of user in such sheet type setting operation. The apparatus is equipped with first detectors for detecting a width dimension of a recording medium, a second detector for detecting a surface characteristic of the recording medium, and a discriminator for discriminating the type of the recording medium based on the results of the first and second detectors.

Abstract: A color blindness dialog box in a Properties window includes a color blindness process mode checkbox enabling a user to select a printing process designed for color blindness. When the color blindness process mode checkbox is checked, it is determined whether the image to be printed includes problematic areas for people with color blindness. If so, image data for these areas is extracted and displayed in a popup window. Subsequently, a borderline process is performed to form a borderline on either or both of the border areas and of text data and graphics data. Thus, the problematic areas are extracted and processed properly so that the problematic areas will become easy to distinguish.

Abstract: If a plurality of print jobs is received irregularly, this invention makes it possible to perform a proper double-sided printing on a print medium. The printing apparatus of this invention comprises: print medium transport unit; printing means; discharge unit for discharging the print medium from the transport path; and double-sided printing control unit for controlling these unit. When the printing of a last page of print data based on a preceding print command is ended on the first surface of a print medium, the double-sided printing control unit does not discharge the print medium and has the print medium, whose first surface was printed, stand by in the transport path. Then, when the next print command is input, a first page of print data in the next print command is printed on the second surface of the print medium.

Abstract: A color image forming apparatus is described. The color image forming apparatus may includes: a belt that travels in a prescribed direction; a plurality of image carriers arranged in parallel in the prescribed direction, and opposed to the belt and carrying developing agent images of different colors respectively; a backup roller arranged in opposed relation to the belt; a cleaning roller arranged in opposed relation to the backup roller with the belt sandwiched therebetween, and adsorbing an adherent to the belt by a potential difference produced between the backup roller and the cleaning roller; and a discharge member opposed to the belt between a position more downstream in the prescribed direction than a position where the cleaning roller is opposed to the belt and a position more upstream in the prescribed direction than a position where the image carrier arranged on the most upstream side in the prescribed direction is opposed to the belt, for discharging the belt.

Abstract: A system of printers uses replicable toner boxes, which each has a unique serial number. Each printer determines once the toner box is empty. At this time, the printer registers the serial number of the used toner box in used toner box list in a memory. Each time a toner box is mounted in the printer, the printer reads and compares the serial number of the freshly inserted toner box with the serial numbers in the list in the memory. If the serial number of the presently mounted toner box matches any in the list, this means that the toner box has previously been judged to reach life end, so the printer displays a message that the toner box is not suitable for use in the printer and prevents further printing operations until the toner box is replaced with a new one.
