Method of data communication between application program and printer driver, and program therefor

摘要

An information processing apparatus and method. The apparatus comprises a generation unit configured to generate a named shared memory that can be accessed by both an application which runs with a first bit number and a printer driver which runs with a second bit number different from the first bit number. A storing unit is configured to store information in the named shared memory generated by the generation unit, and an acquisition unit is configured to acquire the information stored by the storing unit from the named shared memory generated by the generation unit. The storing unit is executed by the printer driver, and the acquisition unit is executed by the application.
