An information processing apparatus which can communicate with a printing apparatus that operates in the first electric power state in which electric power necessary for a status response to an external request is supplied and the second electric power state in which no necessary electric power is supplied includes an acquisition unit which acquires a shift notice from the first electric power state to the second electric power state that is transmitted from the printing apparatus, and a control unit which hastens access to the printing apparatus on the basis of the shift notice acquired by the acquisition unit.

Information processing apparatus, information processing method, program, and storage medium

It is an object to allow an output apparatus to certainly recognize an error when the error occurs at the time of a data transfer using an upper layer (IEEE 1284.4). In a communication system in which an information processing apparatus and an output apparatus can communicate data by using an interface constructed by the upper layer (IEEE 1284.4) and a lower layer (IEEE 1284), when the information processing apparatus detects an error at the time of a data communication using the upper layer, a predetermined command (device ID request) specified in the lower layer is used in order to allow the output apparatus to recognize the occurrence of the error.

Communication system, information processing apparatus, output apparatus, control method, and memory medium

A printer serving as an output destination can be automatically set from print data. Further, in order to search an optimum printer during a series of operations within a range from the issue of a print command to the printing and improve a working efficiency of the user, whether the data whose printing has been instructed by an application is a spool designated print job or not is discriminated (S). When it is spool designated, a spooler interprets a DDI function, generates intermediate data, and spools as intermediate data into a spool file (S). Whether all drawing functions outputted from the application have been spooled in the spool file or not is discriminated (S). If YES, a print destination changing process is executed (S). A print destination is changed and a network printer held in an RAM is updated. After that, the processing routine is returned to step Sand the above processes are repeated.

Searching for printers over a network using intermediate print data

It is an object to allow an output apparatus to certainly recognize an error when the error occurs at the time of a data transfer using an upper layer (IEEE 1284.4). In a communication system in which an information processing apparatus and an output apparatus can communicate data by using an interface constructed by the upper layer (IEEE 1284.4) and a lower layer (IEEE 1284), when the information processing apparatus detects an error at the time of a data communication using the upper layer, a, predetermined command (device ID request) specified in the lower layer is used in order to allow the output apparatus to recognize the occurrence of the error.

A printing system has a host apparatus (information processing apparatus) and a printing apparatus (output apparatus) for performing a printing operation in accordance with data supplied from the host apparatus. A plurality of communication channels are provided between the host apparatus and the printing apparatus. The numbers of packets transmittable and receivable in each communication channel are checked. When there is no packet transmittable to the printing apparatus from the host apparatus, the host apparatus issues a request, after a lapse of a predetermined delay time, to instruct the printing apparatus to inform the host apparatus of the number of valid packets. The delay time for issuing a subsequent request to the printing apparatus for the notification of the number of valid packets is adjusted in accordance with the previous delay time and the number of packets obtained in response to the previous request from the host apparatus.
