Data processor saving data indicating progress status of printing process retrievable by client

摘要

A data processor and a host device are bi-directionally communicably connected to each other. The data processor includes a process-executing unit and a progress-status-saving unit. The process-executing unit executes a prescribed process when a process-requested file is written in a prescribed folder. The progress-status-saving unit saves progress status data indicating a progress status of the prescribed process so that the progress status data is retrievable by the host device.
