Abstract
In a system of a data processing apparatus coupled to a printer, the apparatus sends a status information transmission request to the printer and, in response, receives status information from the printer. The status information includes ink storage identification information written in a memory contained in an ink storage, device identification information identifying the printer in which the ink storage is installed, and ink usage amount information for use by the printer in calculating a remaining ink amount.
