More than one image forming devices which provide detecting means of environmental conditions and sending means of the information of the said detected conditions and a print server are connected through a network. The method includes: a) routing an active call path associated with the mobile device to a voice-to-text conversion system, b) capturing audio from the active call path for a period of time, and c) converting the captured audio to a text memo to create a voice-to-text memo. For example, the programming circuit can include a switch configured to select one of N programming currents for programming the at least one resistive memory element, where each of the N programming currents has a unique combination of current direction and magnitude, with N corresponding to the number of resistance states of the at least one memory element.
