An information processing apparatus includes an acquiring unit for acquiring information stored in a memory of a printing device connected through a bidirectional interface, and a selecting unit for selecting a printer driver corresponding to the information acquired by the acquiring unit from a plurality of printer drivers on the basis of the information.

Information processing apparatus

An information processing apparatus which outputs data to an electronic device. Information indicating a data processing ability of the electronic device is first obtained, whereupon data processing means is controlled so as to process the data output to the electronic device depending on the data processing ability indicated by the information so obtained.

Information processing apparatus and output apparatus

An information processing apparatus includes an acquiring unit for acquiring information from a printer connected through a bidirectional interface, and a control unit for controlling a display status of a virtual printer, which is displayed on a display screen and represents the printer, on the basis of the information acquired by the acquiring unit. An output apparatus includes a setting unit for setting an operating environment, and a changing unit for changing operating environment information set by the setting unit on the basis of information acquired from an information processing apparatus connected through a bidirectional interface.

In a printing apparatus in which a part of the execution program is downloaded from the host computer, the invention allows the user to easily known the copyright information of the execution program and to select the use of such copyright. The host computer sends print data to the laser beam printer constituting the printing apparatus and downloads a part of the execution program. At the same time, the copyright information and the license information of the execution program are transmitted to the laser beam printer. The control unit of the laser beam printer processes the data based on the execution program, thereby recording the data on the recording sheet, and displays the copyright information and license information on the operation panel. Observing the display, the user selects whether or not to obtain the license by the operation panel.

Printing apparatus, data output apparatus and computer readable memory medium

An information processing apparatus acquires identification information which specifies an interpreting program for interpreting a device control language, the specified interpreting program being operable in an external device connected to the information processing apparatus. It is discriminated whether a selected first control program corresponds to the device control language interpreted by the specified interpreting program. If it is discriminated that the selected first control program does not correspond to the device control language interpreted by the specified interpreting program, a second control program corresponding to the device control language interpreted by the specified interpreting program is selected from a plurality of control programs. Data is output to the external device using the first control program or, if it is discriminated that the first control program does not correspond to the device control language, the selected second control program.

Information processing apparatus with device control language based program selection

An information processing apparatus for communicating information with an information device. The information processing apparatus accesses virtual device image data representing an image of the information device, obtains status information representing a status of the information device from the information device through a bidirectional interface, and controls a display to display a virtual device image of the information device based on the accessed virtual device image data and the obtained status information. The virtual device image is a visual representation of the physical appearance of the information device in the status represented by the obtained status information.

A printing apparatus and a printing processing method are provided in which content of print information is discriminated. A variable is initialized if the result of discrimination indicates the start of a printing job, and the variable is counted up of the result of discrimination indicates start of the next page. In a case where trouble such as jamming occurs during processing of this print information, at which page from the start of printing this trouble occurred is calculated from the variable, and the page number obtained is outputted upon being incorporated in information indicative of the fact that trouble has occurred. As a result, it is possible to output information indicating at which page, from the start of a printing job, trouble such as jamming occurred.

Printing apparatus and printing processing method

A printer includes a discriminating section for discriminating meaningless and meaningful internal parameters in a current internal condition, and an output section for outputting the meaningful and meaningless internal parameters while clarifying a difference therebetween on the basis of a discrimination result obtained by the discriminating section. An internal condition output method is also disclosed.

Printer and internal condition output method

An information processing apparatus comprises acquiring means for acquiring a memory capacity of a printer connected through a bi-directional interface, compare means for comparing the memory capacity acquired by the acquiring means with a capacity of data to be outputted to the printer, and determination means for determining a memory size of a memory of the printer in accordance with the comparison result. An output apparatus comprises receiving means for receiving memory size information determined by a capacity of data to be outputted from an information processing apparatus connected through a bi-directional interface and a capacity of a memory for storing the data, from the information processing apparatus, and setting means for dynamically setting a size of the memory for storing the data in accordance with the memory size information received by the receiving means.
