Abstract

A method is directed to using a multifunction printer to identify pages of a printed document that have a specified text string. The method comprises electronically converting, with the multifunction printer, a plurality of pages of the printed document to a plurality of electronic text pages corresponding to the printed pages. The multifunction printer electronically searches the plurality of electronic text pages to identify which electronic text pages include the specified text string. The multifunction printer then communicates the identified electronic text pages to the user.

communicating to a user, via the multifunction printer and independent of the computer without further interaction of the user at the user interface, the identified electronic text pages via at least one of;

automatically printing, via the multifunction printer and independent of the computer, the identified electronic text pages as soon as those respective electronic text pages are identified as having the at least one text string;

or

automatically printing, via the multifunction printer and independent of the computer, a summary of the identified electronic text pages, as soon as those respective electronic text pages are identified as having the at least one text string.

2. The method of claim 1 wherein electronically converting comprises:

scanning the plurality of pages of the printed document, via the multifunction printer and independent of the computer, to produce a digital image file; and

performing an optical character recognition function on each page of the digital image file to produce a plurality of electronic text pages which correspond to the plurality of pages of the printed document.

3. The method of claim 2 wherein scanning the digital image file comprises producing a plurality of digital image pages, with each digital image page corresponding to each page of the printed document;

and

wherein performing the optical character recognition function comprises performing the optical character recognition function on each of the digital image pages to produce a plurality of electronic text pages corresponding to the pages of the printed document.

4. A method of identifying one or more pages of a printed document that include at least one specified text string, the method comprising:

scanning the pages of the printed document, exclusively via the multifunction printer, to produce a digital image file of the pages of the printed document;

specifying at least one text string, exclusively via a user interface of the multifunction printer prior to or during scanning of the pages, that is to be identified in the pages of the printed document;

performing, exclusively via the multifunction printer, an optical character recognition function on the digital image file to produce an electronic text file corresponding to the pages of the printed document;

automatically, electronically searching, exclusively via the multifunction printer, the electronic text file to identify electronic text pages of the electronic text file that include the at least one specified text string;

automatically communicating, exclusively via the multifunction printer without further user engagement of the user interface and without displaying the identified electronic text pages at the multifunction printer, only the identified electronic text pages, via at least one of;

automatically printing the identified electronic text pages exclusively via the multifunction printer as soon as the respective identified electronic text pages are identified as including the at least one specified text string;

or

automatically printing a summary of the identified electronic text pages exclusively via the multifunction printer as soon as all of the respective identified electronic text pages are identified as including the at least one text string.

5. The method of claim 4 wherein scanning the pages includes scanning each page separately so that each page produces a separate digital image file.

6. The method of claim 5 wherein performing an optical character recognition function comprises performing the optical character recognition function on each page of the digital image file to produce a separate electronic text page for each page of the printed document.

14. The method of claim 4, comprising:

storing the electronic text file and the digital image file in a buffer of a memory of the multifunction printer for a period of time extending only through completion of the automatic printing of the at least one identified electronic text pages or the automatic printing of the summary of the identified electronic text pages.

7. A multifunction printer comprising:
