  • Patent number: 7403303
    Abstract: The present invention provides a printing system and a printing method that avoids interrupting a printing process in order to execute a calibration process, while stably reproducing colors. A second printer includes a printing engine having a temperature sensor, a density sensor, and a density sensor and a print controller which acquires information from the various sensors in the printing engine to provide calibration process information to a first printer. The print controller includes a density converted characteristic generating section that converts output density values corresponding to density values inputted to the first printer so that the output density values exhibit an ideal characteristic. The density converted characteristic information generating section generates density converted characteristic information. The first printer receives the density converted characteristic information and executes a printing process while carrying out a density conversion.

  • Patent number: 7099032
    Abstract: In performing a printing operation, upon designating the type of paper by inputting it, a paper type table is searched to determine whether the designated type of paper requires a special printing operation, such as reverse feeding and printing. If the above-mentioned operation is required, an appropriate printing operation command is issued. If the above-mentioned operation is not necessary, a normal printing operation command is issued. A determination is also made of whether the designated type of paper requires a special fixing printing, such as cardboard mode fixing. If the above-mentioned operation is required, an appropriate fixing command is issued. If the above-mentioned operation is not necessary, a normal mode fixing command is issued. An image of print data is then formed and printed.

  • Patent number: 5737737
    Abstract: CCP data as common data, which can be utilized by a plurality of users or applications, are stored in a CCP buffer in units of data types (format IDs). More specifically, the CCP buffer stores one CCP data per format ID. Upon reception of a request for CCP data from an application, the system analyzes this request to acquire the format ID of the CCP data requested by the application. The system searches CCP data having a format ID coinciding with the requested format ID from data management information of CCP data. The system passes the searched CCP data to the application, and ends processing. In this manner, CCP data can be stored in correspondence with a plurality of data types, and required CCP data can be easily selected by using its format ID. Therefore, operability with respect to common data can be improved, and work efficiency of users can be improved.

  • Patent number: 5352821
    Abstract: The present invention is directed to novel 2,5-dichlorophenylthioglycolic acid derivative, a process for their production and a process for producing the desired product 2,5-dichlorophenylthioglycolic acid derived from said novel compounds. 2,5-dichlorophenylthioglycolic acid derivative of the present invention can be obtained by reacting 2,4,5-trichlorobenzensulfonates and thioglycolic acid in the presence of base, and said desired product can be obtained by desulfonating said compound in an aqueous solution of mineral acid. Novel 4-carboxymethylthio-2,5-dichlorobenzenesulfonates of the present invention can be used advantageously as an intermediate for the production of 2,5-dichlorophenylthioglycolic acid. The use of said intermediate makes it possible to obtain the desired product in a decreased process steps with high yield. In addition, it poses no problem of environmental pollution as pointed out with conventional methods because it uses no heavy metals.
