Refer now to FIG. 2, which illustrates a schematic view of a mobile device used in connection with the printing device in accordance with one embodiment of the present invention. As shown in FIG. 2, the mobile device present invention may include a computer readable medium 202 to store computer program instructions to control a majority of the processing required to output a file at the printing device 100, such as an image file and/or an audio file.
In one embodiment of the present invention, the computer readable medium 202 may be, for example but not limited to any physically tangible device that operates using magnetic, electronic, electromagnetic, optical, or semiconductor components. In particularly, the computer readable medium 202 may be a memory card, a hard disk, a portable computer diskette, a random access memory, a read-only memory (ROM), or any other physically tangible medium that can contain, store, communicate, or transport a program for use by or in connection with the mobile device 200.
In accordance with the present invention, the computer readable medium 202 may store computer program instructions to be sent to the printing device 100 to establish control of the printing device 100.

In accordance with the present invention, the computer readable medium 202 may store computer program instructions to perform such editing at the mobile device 200. As a result, the edited image file may be processed by the processor 206 of the mobile device 200 instead of the printing device 100. When the edited image file is sent to the printing device 100, the communication element 102 of the printing device 100 may simply send the edited image file to the printing element 104 and activate the printing element 104 to output the edited image file.
In another embodiment of the present invention, the mobile device 200 may also send music files to the printing device 100. In such an example, the computer readable medium 202 may store computer program instructions to be sent to the printing device 100 to establish the communication connection. As the communication connection is established, the computer program instructions may send one selected music file or a number of selected music files from its local memory to the printing device 100. In one example, the computer program instructions may randomly send a music file from a local playlist to the printing device 100. When receiving the music files from the mobile device 200, the communication element 102 of the present invention may directly send the file to the audio outputting element 106 and activate the audio outputting element 106 to play the music files. As such, the printing device 100 may be used as a music player without storing the music files locally.
In one embodiment of the present invention, the mobile device 200 may include a transceiver 204. In accordance with the present invention, the computer readable medium 202 is electrically coupled to the transceiver 204 such that the computer program instructions stored in the computer readable medium 202 may be sent to the communication element 102 of the printing device 100. Additionally, the music and/or image files stored in the computer readable medium 202 may also be sent to the communication element 102 of the printing device 100.
In one embodiment of the present invention, the mobile device 200 may include a user interface 208. The user interface 208 of the present invention may display a selection of options for a user to operate the mobile device 200. Additionally, the user interface 208 of the present invention may display a selection of options for the user to operate the printing device 100 once a communication connection is established between the printing device 100 and the mobile device 200. For example, if a user wishes to edit a picture file before printing it out, the user may select a desired photo frame, such as a gold or silver color frame, or change the color saturation of the picture at the mobile device end through the user interface 208. Additionally, the user may also select the printing options, such as picture size, resolution, the number of prints, etc. at the mobile device end through the user interface 208. In other words, once the communication connection is established between the printing device 100 and the mobile device 200, the user interface 208 of the mobile device 200 may display the user menu shown in the user interface 108 of the printing device 100. As such, the mobile device 200 may take control of the printing device 100.

In one embodiment of the present invention, the second mobile device 320 may wish to send an image file to the first mobile device 310. In accordance with the present invention, before a user sends the image file to the first mobile device 310, the user may first edit the image file from the second mobile device 320. For example, the user may wish to add a photo frame, such as a gold or silver color frame, to the image file. In another example, the user may wish to adjust the color saturation of the image file. In accordance with the present invention, the computer readable medium 322 may store computer program instructions to perform such editing at the second mobile device 320. As a result, the edited image file may be processed by the processor 326 of the second mobile device 320 instead of the first mobile device 310. When the edited image file is sent to the first mobile device 310, the communication element 312 of the first mobile device 310 may simply send the edited image file to the printing element 3142 and activate the printing element 3142 to output the edited image file.
In another embodiment of the present invention, the second mobile device 320 may also send music files to the first mobile device 310. In such an example, the computer readable medium 322 may store computer program instructions to be sent to the first mobile device 310 to establish the communication connection. As the communication connection is established, the computer program instructions may send one selected music file or a number of selected music files from its local memory to the first mobile device 310. In one example, the computer program instructions may randomly send a music file from a local playlist to the first mobile device 310. When receiving the music files from the second mobile device 320, the communication element 312 of the present invention may directly send the file to the audio outputting element 3144 and activate the audio outputting element 3144 to play the music files. As such, the first mobile device 310 may be used as a music player without storing the music files locally.
In one embodiment of the present invention, the second mobile device 320 may include a transceiver 324. In accordance with the present invention, the computer readable medium 322 is electrically coupled to the transceiver 324 such that the computer program instructions stored in the computer medium 322 may be sent to the communication element 312 of the first mobile device 310. Additionally, the music and/or image files stored in the computer readable medium 322 may also be sent to the communication element 312 of the first mobile device 310.
In one embodiment of the present invention, the second mobile device 320 may include a user interface 328. The user interface 328 of the present invention may display a selection of options for a user to operate the second mobile device 320. Additionally, the user interface 328 of the present invention may display a selection of options for the user to operate the first mobile device 310 once a communication connection is established between the first and second devices 310, 320. For example, if a user wishes to edit a picture file before printing it out, the user may select a desired photo frame, such as a gold or silver color frame, or change the color saturation of the picture at the second mobile device end through the user interface 328. Additionally, the user may also select the printing options, such as picture size, the number of copies to print out, etc. at the second mobile device end through the user interface 328. In other words, once the communication connection is established between the first and second mobile devices 310, 320, the user interface 328 of the second mobile device 320 may display the user menu shown in the user interface 318 of the first mobile device 310. As such, the second mobile device 320 may take control of the first mobile device 310.
