Provided are a halloysite powder and a method for producing the halloysite powder. The halloysite powder contains granules in which halloysite including halloysite nanotubes is aggregated. The granules have first pores derived from the tube holes in the halloysite nanotubes and second pores that are different from the first pores.

A printing apparatus can quickly cancel a print job without any influence on the other subsequent print jobs when a print cancel instruction is issued. During printing, if a print cancel instruction is inputted from a printer operation unit, a printer function manager notifies a print command interpreter of the cancellation. The print command interpreter searches data processed at that time in a transmission/reception buffer for an end mark command indicating the end of the cancelled job. Then the print command interpreter deletes the data before the end mark command.

Printing apparatus and printing system, control method, storage medium and program

There is provided an image processing apparatus having communicating and recording functions. This apparatus comprises: a communication control unit to communicate an image; a memory to store image information received from the communication control unit; a CRT display to display the image information stored; a designating device to designate a desired area in the image displayed on the CRT display; a printer to print only the area designated by the designating device from the image information stored; and, preferably a second designating device to designate the number of copies of the image information which are to be printed by the printer. With this apparatus, the necessary area in the received image information can be printed alone, in just the necessary number of copies. Thus losses of the paper and printing time can be prevented.

Partial display printing, secure-communication and multiple copying

A printer includes a receiver for receiving a first command and a second command from an external apparatus, and an execution device for executing the first command when the receiver receives the first command, and for executing the second command in preference to the first command when the receiver receives the first command and then receives the second command.

Printer control with monitor function

There is provided an image processing apparatus having communicating and recording functions. This apparatus comprises: a communication control unit to communicate an image; a memory to store image information received from the communication control unit; a CRT display to display the image information stored; a designating device to designate a desired area in the image displayed on the CRT display; a printer to print only the area designated by the designating device from the image information stored; and, preferably, a second designating device to designate the number of copies of the image information which as to be printed by the printer. With this apparatus, the necessary area in the received image information can be printed alone, in just the necessary number of copies. Thus, losses of the paper and printing time can be prevented.

Partial-display printing, secure communication and multiple-copying

There are provided a color image forming method with liquids, capable of ensuring sharpness and high density in basically all the color images, and a recording apparatus therefor. This invention employs a black ink of relatively superior diffusibility and color inks of relatively superior penetrability, different in color from the black ink, and is characterized by forming the boundary area of a black image area with the color inks instead of the black ink.

Ink-jet recording method employing inks of different characteristics and

A host computer checks the frequency of type data such as a character code or a graphic pattern in print data. Type data with a high frequency is registered in a registered character management area in correspondence with a data ID and sent to a printer. The printer registers the received ID and data in a print data registration area. Thereafter, the host computer sends print data obtained upon replacement of the type data with the ID to the printer. The printer identifies an ID included in the print data, replaces the ID with the corresponding type data, and outputs the print data. With this processing, data with a high use frequency can be registered in the printer. Therefore, the data transfer amount from the host computer can be decreased, and the printing processing speed is increased. In addition, since the frequency is totalized, the memory in the printer can be effectively used.

Printing system with means to extract data type before printing on a

To prevent an ink blurring on the recording medium, the ink jet recording apparatus for ejecting ink droplets onto the recording medium to record an image includes a plurality of recording heads, each having a plurality of ejecting ports and ejecting different inks; a data storage device for storing printing data and non-printing data for each of the recording heads; a boundary detector for detecting a boundary between the printing data and the non printing data of one of the recording heads in accordance with the printing data stored in the storage device; and a judging an adjusting device for judging whether printing data of other heads continues for more than a predetermined number of dots at the boundary detected by the boundary detector; and a thinning device for converting some of the printing data of the other heads to non printing data when the judging means determines that the printing data of the other heads continues for more than the predetermined number of dots.

Ink jet recording apparatus and method capable of preventing ink

An electronic apparatus utilizing an external memory such as a floppy disc or a cassette tape has a signal generator for generating a signal to indicate the interchange of the external memory. Upon detection of the signal, the interchanged external memory is properly handled.

Electronic apparatus for proper handling of interchangeable memory

Electronic apparatus having a mode setting switch, keys for keying in information, a memory for storing information to be processed entered by the keys and the mode setting switch, and provisions for controlling the memory to accept information from the mode setting switch only when changes are made in such mode information.
