Abstract

An all-in-one (AIO) printer is provided, in which its bulk input device (scanner) is employed as a data reader of audio information, and its bulk output device (print engine/printhead) is employed as a data burner (or writer) of audio information. The present invention acts as a sound recording device and a sound playback device that may be incorporated within an AIO printer. If the AIO printer is combined with a host computer that includes a microphone and speakers, then no physical hardware need be added to a standard AIO printer to perform the functions of the present invention of recording and storing audio information.

(c) lossy compressed data;

(c) a WAV file, and (d) an MP3 file.

7. A sound recording and image forming system, comprising:

a memory circuit for storage of data;

a print engine;

a microphone;

an interface circuit; and

at least one processing circuit that is configured to control a flow of data;

(a) from said interface circuit, and (b) between said print engine and said memory circuit;

wherein;

said microphone generates an audio-frequency signal from received sound waves;

said interface circuit receives and converts said audio-frequency signal generated by said microphone into a first data signal, wherein at least a portion of said first data signal comprises information representative of said received sound waves; and

said at least one processing circuit is further configured;

(c) to receive said first data signal from said interface circuit, (d) to convert said first data signal into a second data signal comprising a print job, and (e) to transfer said second data signal to said print engine for recording as a hard-copy printout upon a print media, in which at least a portion of said hard-copy printout is representative of said received sound waves; and

an optical scanner that generates a third data signal from scanning a sheet of hard-copy media, wherein;

at least a portion of image information on said hard-copy media comprises audio information;

at least a portion of said third data signal is representative of said audio information; and

said at least one processing circuit is further configured for one of;

(f) to convert said third data signal into a fourth data signal comprising a print job, and to transfer said fourth data signal to said print engine for recording as a hard-copy printout upon a print media, in which at least a portion of said hard-copy printout is representative of said audio information; and

(g) to store one of said third data signal and said fourth data signal as a file in a bulk memory device, wherein said file comprises one of;
