A modular garment kit including a brassiere and a plurality of garment members that are interchangeably attached with snaps or hook and loop fastening to the brassiere. The method includes intercepting a request from an application to an encryption component of an operating system to encrypt the data and acquiring encrypted data generated by the encryption component in response to the request. When a power supply is scheduled to be turned off, a message indicating it is supplied to a host computer that uses the printer, or job conditions are saved, and the host apparatus is informed of the saved job conditions after the power supply is turned on again. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.
