A data processing apparatus having a construction for guiding a transported medium conveyed from a curved transportation unit enables opening and closing the guide unit. The data processing apparatus 1 has an intermediate roller 39 and guide portion 38 constituting a curved transportation unit 23 inside the printer case 7, and a paper feed roller pair 25 and 26 for nipping and conveying paper P conveyed from the curved transportation unit 23 disposed a specific distance from the curved transportation unit 23. The guide portion 38 has an auxiliary guide member 51 and can move circularly open and closed in unison with an outside wall unit 16. The auxiliary guide member 51. projects toward the paper feed roller pair 25 and 26 and guides the paper P. An auxiliary guide linking mechanism 53 causes the auxiliary guide member 51 to retract away from the paper feed roller pair 25 and 26 in conjunction with the unlocking operation of opening/closing levers 41 and 42.

A print medium and methods are provided for producing a die-cut portion easily separable from the print medium, thereby shortening the required time to separate the die-cut portion and reducing wasted consumption of print media. The print medium may include die-cut portions having a contour of a wristband, such as those used in a hospital on the wrist of a patient. The die-cut portions are formed sequentially at a constant interval on the print medium, and die-cut lines are formed between each die-cut portion as lines connecting adjacent die-cut portions. The print medium may be automatically cut at the position of a severance line perpendicular to the die-cut line referenced by a cut mark on the print medium. Because the edges of the severed print medium piece are perpendicular to the die-cut lines, separating the die-cut portion from the print medium can be easily started along the die-cut line.

A first half-tone processing means 110 half-tone processes image data blocks using an error diffusion method. A second half-tone processing means applies a half-tone process for error value calculation on a leading portion of each image data block before the normal half-tone processing. Two error buffers store the error values output by the first half-tone processing means successively to the leading error values already stored by the second half-tone processing means. Two data buffers store the process result from the first half-tone processing means. The first half-tone processing means starts half-tone processing the image data blocks using the leading error values stored in the two error buffers.

A printer having multiple stages of nozzles is controlled to avoid or minimize blank space between print portions when printing on roll paper. A controller in communication with the printer is configured to determine if last partial print data to be printed contains blank raster data. If so, the controller calculates the difference between a total number of rasters in the first through the last partial print data and the number of blank rasters in the last partial print data, prints the last partial print data, and controls the paper transportation mechanism to advance the roll paper only the calculated distance to eliminate excess blank space between print portions. The functionality of the controller is also embodied in a method for controlling a printer as described above.

A printing system and method for printing to roll paper with the advancement of the roll paper controlled such that printing of blank raster data at the end of the printed portion of the roll paper is minimized. The printing system has a raster data generating means for producing raster data from print data where the raster data is data for printing one line, a partial print data generating means for generating partial print data by allocating the raster data to each stage of nozzles disposed to a print head in the printer, a storage means for storing the partial print data, means for moving the print head in a main scanning direction and for advancing the roll paper in a sub-scanning direction while printing the partial print data stored in the storage means to the roll paper and program means to determine if the last partial print data being printed contains blank raster data continuously to the end thereof and if so to control the advance of the roll paper to a distance equal to the difference between the total number of rasters that can be printed by the print head and the number of blank rasters in the last partial print data.

A read/write processing device including: a transport path, adapted to transport a medium therethrough; a read/write unit, adapted to read or write data on the medium and provided at a part of the transport path; a transport mechanism, provided with a first feeding roller and a pressing member adapted to transport the medium to the read/write unit while the pressing member presses the medium toward the first feeding roller; a gap adjusting mechanism, operable to adjust a gap between the read/write unit and the medium in the trasnsport path; a medium release mechanism, operable to release the mdium from the first feeding roller and the pressing member; a detector, operable to detect a jam of the medium in the transport path; and a controller, operable to control the gap adjusting mechanism to wide the gap, when the detector detects the jam.
