Abstract: A printer includes a memory storing instructions for authenticating a login user and determining whether a user identity information is included in a print data. When the user identity information is included in the print data, the instructions cause the printer to determine whether the login user is identical with a data sender user having sent the print data. When the login user is identical with the data sender user, the instructions cause the printer to print the pint data. When the login user is not identical with the data sender user, the instructions cause the printing portion to not print the print data. When the user identity information is not included in the print data, the instructions cause the printer to print the print data irrespective of whether the login user is identical with the date sender user.

Abstract: A call and recorded information management server transmits a requested call identification ID for recognition and an incoming call number corresponding to the ID, to a voice recognition server, which searches for the recognition engine corresponding to the number of the received call, and adds the received ID to a recognition queue. The voice recognition server requests the call and recorded information management server to obtain recorded data by the received ID. The call and recorded information management server transfers the recorded data corresponding to the ID to the voice recognition server to perform voice recognition by the corresponding recognition engine on the recorded data corresponding to the call identification ID stored in the recognition queue, and stores the result as text data. Thus, the most appropriate voice recognition engine can be used and the recognition rate of voice recognition can be increased.
