An output apparatus includes a cartridge which contains a recording material. A detector is provided in the apparatus for detecting the remaining amount of the recording material in the cartridge. A controller is provided in the apparatus for storing the cumulative consumed amount of the recording material in a non-volatile memory unit. Thus, the remaining amount of the recording material is determined.

Print data of each page sequentially sent from a host computer and second print data converted from registered first print data and stored in a memory are developed on the memory to generate a print image under the control of CPU. An overlap print by a printing unit is controlled in accordance with the generated print image. Even if the print style of input print data of each page changes, optimum second print data can be generated in a short time without giving a load on memory resources. Therefore, a print process time of formatted print data such as forms can be shortened and a desired overlay print can be performed efficiently.

There is disclosed an information processing apparatus, such as a printer, capable of selectively using plural control programs by utilizing an external memory, such as a program cartridge, containing additional programs. When a switching of control program is requested for example by a switch, the start address of the requested program is indirectly obtained by referring to a fixed address of the memory cartridge containing the requested program.

In an information processing apparatus for causing a printer to execute a printing operation by registering a font therein, there is disclosed a configuration allowing the information processing apparatus to manage the font to be registered in the printer thereby preventing the failure in the printing operation. The information processing apparatus issues a command for reserving a memory for font registration in the printer, then calculates the available capacity based on the reserved memory capacity at the transfer of the font to the printer, and executes transfer or deletion of the font based on thus calculated available capacity.

A data processing apparatus includes an input unit for inputting printing data, a processing unit for processing the printing data input from the input unit and outputting image data, a storage unit for storing the image data, and a setting unit for arbitrarily setting an area capable of storing the image data stored in the storage unit.

Data processing apparatus

An output method and apparatus is provided for storing first control information for controlling an output operation based on externally supplied data and for storing command information for commanding modification of the first control information to second control information that is different from the first control information, and for modifying the first control information to the second control information to control the output operation based on the second control information in accordance with the stored command information, wherein the output operation can be executed based on the first control information.

Method and apparatus for printing data in accordance with a previously

An output apparatus such as a printer is controlled by a control program. A first control program is stored in a fixed storage medium, and a second control program having a different operation than the first control program is stored in a detachable storage medium. The two control programs are selectively used, based on data received from a host computer.

Output method and apparatus using the same

An image processing apparatus for receiving a plurality of data groups, each of which belongs to a different command system of an external apparatus. A data analyzer is included in each command system. A data receiver receives the data from the external apparatus, and a judgment is made as to whether each of the data groups received by the data receiver contains the data analyzer corresponding to the command system of the corresponding data group. A print controller bypasses a data group of a command system judged not to include the data analyzer, and printing is disabled for that data group.

An electronic equipment includes a memory for storing information necessary for the execution of control programs and identification information which identify the control programs. A first check determines whether the identification information of the control program to be executed is equal to the identification information stored in the memory. A second check determines whether there is a vacant area in the memory when the decision by the first check indicates non-equality, and a control unit stores the information necessary for the control program to be executed in the memory together with the identification information thereof when the second check detects a vacant area.

Electronic equipment including non-volatile memory means for storing

A data processing apparatus includes a first image signal generating source for sending a first image signal to a printer unit for printing the first image signal; a second image signal generating source for generating a second image signal different from the first image signal, the first image signal generating source being connectable to the second image signal generating source and having a combined image signal output mode for outputting a combined signal of the first and second image signals to the printer unit; and an inhibition unit for inhibiting a change from the combined image signal output mode to another image signal output mode while the printer unit is operating.

An image data output apparatus is connected to an image scanner and a data processor (host computer). The image data output apparatus includes interfaces, a data converter, a video signal generator, an LBP engine unit, and the like. Multi-level image data scanned by the image scanner is converted by the data converter into data having a desired data format corresponding to the data processor. The converted data is output to the data processor through the corresponding interface. Meanwhile, the scanned image data is also supplied to the video signal generator and is converted to a drive signal for driving a semiconductor laser of the LBP engine unit.
