It is possible to identify a frequent error factor based on the printer environment output request from the input means and present the user with the memory resource allocation information that matches the current memory resource use environment as a print result.

According to the sixth invention, the type of the external resource connected to the connecting means is determined, and the memory allocation for each type set in the memory resource is changed based on the type determination result. Therefore, even if an external resource is connected and the usage environment of the memory resource changes, the processing for suppressing the occurrence of error processing, warning processing, etc. can be automated.

According to the seventh invention, since the error information stored in the non-volatile storage means is compared with a predetermined value to change the memory allocation set in the memory resource,
It is possible to automate the process of identifying frequently occurring error factors and optimizing the allocation of memory resources so as to match the current usage environment of memory resources.

According to the eighth aspect, the type of the external resource connected to the connecting means is determined, and the memory allocation for each type set in the memory resource is changed based on the type determination result. At the same time, the memory allocation set in the memory resource is changed by comparing the error information stored in the non-volatile storage means with a predetermined value, so that processing for suppressing occurrence of error processing, warning processing, etc. is automated. In addition to enabling the above, it is possible to automate the process of identifying the frequently occurring error factor and optimizing the allocation of the memory resources so as to match the current usage environment of the memory resources.

According to the ninth aspect, the allocation information which can be recommended for the memory resource by judging the type of the external resource connected to the connecting means and comparing the type judgment result data with a predetermined value. Is derived and the derived allocation information is printed based on the input of the printer environment output request. Therefore, if there is an input of the printer environment output request, the recommended memory resource when the external resource is connected The process of printing the allocation information of can be automated.

According to the tenth aspect, the allocation information recommended for the memory resource is derived by comparing the error information stored in the nonvolatile storage means with a predetermined value.
Since the derived allocation information is printed based on the input of the printer environment output request, the frequently occurring error factor is specified based on the printer environment output request from the input means to determine the current use environment of the memory resource. It is possible to automate the process of printing the allocation information of the matching memory resources.

Therefore, the effect of optimizing the allocation state of the memory resources and greatly reducing the error processing and warning processing can be obtained.
