The printing control apparatus compares, when printing a bit image, a data set of a transmitted compressed image data to a data set of an untransmitted compressed image data, omits transmission of the data set in the subsequent compressed image data when the data sets coincide with each other, and notifies the printing apparatus that transmission of the data set has been omitted with setting in a printing command. The printing apparatus holds the compressed image data in which the data set has been omitted, and, when it is notified that transmission of the part of the data set has been omitted, generates the bit image by reusing a part of the already existing data set and developing the held compressed image data.

Printing system, printing control apparatus, printing apparatus and method for generating a band compressed image data and print command includes selection of omitting untransmitted data set

A printing apparatus including one or more feeding units includes: a sheet size determining unit which determines a sheet size of a sheet, on which print data are printed, in predetermined order; a print control unit which stores a designated size, which is the sheet size determined by the sheet size determining unit, in a storage unit; a feeding unit selector which selects the feeding unit on the basis of the designated size; and a process selection information storing unit which stores process selection information used to designate a process executed by the print control unit.

Printing apparatus

A printer includes a use status computation section which collects statistics of a use status of an analyzed print job and computes a use frequency and an execution interval of a language translation program based on a result of the statistics, and a resident mode switching section which causes a language translation program with a highest use frequency to initially stay resident in a memory and further causing a language translation program with a high use frequency and a long execution interval to stay resident next to the language translation program with the highest use frequency in the memory.

A printing apparatus that measures a consumption of a colorant during printing, includes a shade level measuring unit that measures a print shade level on a print sheet, a range segment counting unit that counts the number of print sheets falling within each of a plurality of print shade range segments based on the measurement results of the shade level measuring unit, and an output unit that outputs the count results of the range segment counting unit on a per print shade range segment basis.

Printing apparatus, and method and program for controlling printing apparatus

There is provided a color page printer including a print engine operable by a color mode for executing color printing and a monochrome mode for executing monochrome printing, and a control unit for controlling the print engine to generate a printed paper having a content corresponding to received print data. The control unit is a unit equipped with a print number output section for outputting numbers of surfaces printed by a color mode and a monochrome mode of the print engine respectively as a number of color prints and a number of monochrome prints in an engine counter mode, numbers of surfaces printed based on print data for which color print is specified and print data for which monochrome print is specified respectively as a number of color prints and a number of monochrome prints in a driver specified counter mode, and a number of printing surfaces whose printed result was color and a number of printing surfaces whose printed result was monochrome respectively as a number of color prints and a number of monochrome prints in a real counter mode.

A model-specific databaseprovided on a print control memberof a printer stores setting commands for a plurality of print stations, and menu information to be displayed on an operation panel. A maintenance processing memberobtains from the model-specific database, a menu corresponding to the model IDof the print station, and displays the menu on the operation panel exposed at the printer housing. A maintenance operator carries out adjustment of the print station by operating the operation panel. Since processes and the like depending on the model of the print station are concentrated in the maintenance processing memberand the model-specific database, other structures of the print control membercan be configured so as not to depend on the model of the print station.

Printer, an operation panel thereof having a function for doing maintenance of print station

An information processing apparatus is configured as an apparatus for accessing an external date and time management apparatus, such as an SNTP server, to adjust the date and time of an internal clock and as an apparatus for calculating the next date and time adjustment execution date and time so that an error of the internal clock falls within the allowance time specified by the user whenever the date and time are adjusted.

Printer and information processing apparatus

According to a printing system of the present invention, each host performs a process for creating and storing a preview file when transmitting reserve job data to a printing apparatus, and a process for generating and transmitting reserve job data that includes preview file designation data representing the storage location of the preview file. The printing apparatus manages each set of preview file designation data in correlation with reserve job data, and supplies a preview file correlated with reserve job data, or preview file designation data, to the host that requires the preview file.

Printing system, printing apparatus and printing apparatus control program

A printer includes: a print performing unit which can change a structure thereof and in which contents of an executable printing process change depending on the structure; an apparatus name information storing unit which stores a plurality of apparatus name information as identification information of the apparatus coordinated with the structure; and a request responding unit for transmitting the apparatus name information coordinated with the structure at that time when a prescribed request is received among the plurality of apparatus name information to an apparatus transmitting the request.

In a printer having a function of automatically finding out a paper feeder satisfying the condition that the paper size specified in print data and the paper size set in the printer match and then printing, if they match and it is made impossible to find out any paper feeder in which paper remains although print data processing is not complete (paper error state), the user can change the paper size set in the printer and if the paper size is changed to the correct size (print enable state), the printing is continued.
