Abstract: An ink-jet printing apparatus receiving image data from a host computer and prints the image data. If 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.

Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that when writing in an RF-ID tag fails, it is difficult to confirm that, and it is impossible to quickly discriminate a writing successive article from a defective article. SOLUTION: For example, labels whose writing in their incorporated elements fails are sorted by a method for changing the cutting intervals by a cutter, or peeling them, and cut sheets are outputted to different paper ejection trays. Thus, in executing recording on the surface of a medium to be recorded incorporating communicating elements such as the RF-ID tag and writing in the communicating elements in parallel by using a recorder, it is possible to instantaneously discriminate the successive article from defective article of data wiring, and it is possible to sharply increase reliability for the medium to be recorded in which data are recorded and written.

Abstract: PROBLEM TO BE SOLVED: To realize a method and an apparatus in which a decision can be made previously whether recording can be completed on a recording medium being set currently or not with no interruption when recording operation of a relatively large volume of information is performed.
SOLUTION: The recorder comprises a means for detecting the number of remaining sheets of recordable recording media based on information read out from a radio communication device incorporated in a recording medium, a memory for storing the number of remaining sheets thus detected, a means for comparing the number of remaining sheets of recording media stored in the memory with the number of recording sheets to be recorded, and a means for updating the number of remaining sheets stored in the memory.

Abstract: PROBLEM TO BE SOLVED: To reduce a recycle ink to be generated at a discharge recovery operation as much as possible and to suppress decrease of a throughput caused by an ink replenishment. SOLUTION: An inkjet printer 1 has a plurality of recording heads HK-HY each capable of discharging a different color ink, and can record images onto a recording medium P by discharging ink from each of recording heads HK-HY. Each of recording heads HK-HY is provided with a pressure pump 10 and a suction pump 11. In the inkjet printer 1, the discharge recovery operation or ink replenishment can be carried out with the utilization of at least one of the pressure pump 10 and the suction pump 11 for each of recording heads HK-HY separately.

Abstract: PROBLEM TO BE SOLVED: To provide an inkjet recording device and its recovery treatment method, wherein recycled ink liquid or the like to be generated by preliminary discharges is reduced to the minimum, while time required for the recovery treatment is shortened. SOLUTION: Pressure-treatment to pressurize the inside of a recording head is carried out by pressurizing a pressure pump provided in an ink tank. Then, in order that the pressure in the recording head is lowered to an adequate value after the pressurizing operation is completed, the position of the pressure cam provided in each ink tank is grasped based on the count value of a pulse motor, and the number of the preliminary discharges is set for each color, based on a relational table between a predetermined count value and the number of the preliminary discharges to carry out the preliminary discharges. Or, the positions of the pressure cams are adjusted such that the pressure cams are stopped at the same non-pressurizing position through all the ink tanks, and since the positions of the pressure cam become the same thereby, the preliminary discharges are carried out with the same number of the preliminary discharges with respect to all the recording heads.

Abstract translation: 要解决的问题：为了提供一种喷墨记录装置及其回收处理方法，其中通过初步排放产生的再循环油墨等减少到最小，同时缩短了回收处理所需的时间。 解决方案：通过对设置在墨罐中的压力泵进行加压来进行对记录头内部加压的压力处理。 然后，为了在加压操作完成之后将记录头中的压力降低到适当的值，根据脉冲电动机的计数值来掌握设置在每个墨罐中的压力凸轮的位置，并且数量 基于预定计数值和预备放电次数之间的关系表来对每种颜色设定预备放电，以执行初步放电。 或者，调节压力凸轮的位置，使得压力凸轮通过所有的墨水罐停止在相同的非加压位置，并且由于压力凸轮的位置相同，所以预先排出是用 与所有记录头相同数量的初步排放。 版权所有（C）2005，JPO＆NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide an inkjet recorder and a method of inkjet recording capable of achieving the adequate accuracy for reading a code without increasing or decreasing the number of pixels or dots of a bar or a cell forming code information such as a bar code or a two-dimensional code. SOLUTION: A part of or all of dots forming a periphery of a code image are made smaller than dots in the code image except the periphery. By this structure, it is possible to suppress an amount of dots in a black image region protruding into the adjacent white region, the black image region being representing a code image so that the size of the image on a recording medium is roughly matched with a size of a pixel of a bar or a cell forming the code without increasing or decreasing the number of recording pixels of the black image and the white image.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that when continuous label sheets are to be printed sheet by sheet by a label printer having a carriage, a not yet recorded label advancing to the vicinity of a sheet discharge opening must be returned temporarily back to the upstream side of the recording position before being advanced further toward the recording position, and that operation causes a time loss. SOLUTION: When a plurality of TOF (Top Of Form) sensors are arranged on the upstream side and the downstream side of a recording area and a sheet is carried to a recording position while involving inversion carriage, the time required for recording can be shortened because the amount of inversion carriage is small and forward operation following to inversion can be saved.
