Problems solved by technology

The printing of document pages containing little content can result in a needless use of paper.
There is no automated algorithm that can preprocess a document prior to printout that will quickly and reliably improve the efficiency of printout.
Further, the manual process results in a modification of the actual document that would require changing the document back to the version prior to the compression for printing.
However, this feature has limitations in that it only allows very small incremental changes to the printed document.
Further, the changes allowed by this function are also forced to be proportional and has a gating factor in the function to only allow a r

Example

[0026] The present invention provides automated method to reduce the amount of paper required to print certain documents. In application, the method of the invention scans through a document and modifies the document by removing unnecessary space (white space) on the document in accordance to predefined criteria for the document. The modified document is then printed using less paper. The following example shows how the invention can be applied. A person wants to print a 30-page document containing a scripting language source code listing. Upon printing the 30-page document, it is apparent that most of the white space could be eliminated. Additionally the comments could also be removed. The invention adds the preprinting functionality to reduce this amount of white space such that the entire printout is now only 10 pages. To access this function, a person would be presented with options during the printout function to allow such a compressed printout. Configuration changes to the do...

Abstract

A print compression method and system reduces the amount of space required to print a document such that less paper is used during the printing of a document. A user defines criteria, which is used to perform document compression. However, the document compression only applies to the form of document being printed. This compression does not affect the document being edited.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a method and system for printing a document on a page and in particular to a method and system that automatically compresses the amount of information that is to be printed on a page in order to reduce the amount of paper needed to print the information. BACKGROUND OF THE INVENTION [0002] A computer printer is a computer peripheral device that produces a hard copy (permanent human-readable text and / or graphics, usually on paper) from data stored in a computer connected to it. FIG. 1 illustrates a typical computer and printing system. As shown, the personal computer 2 has a display screen 5, a keyboard 6, a coordinate input device (mouse) 7, and a controller body 8. The controller body 8 is connected to the laser printer 3 by a connecting cable 9. Therefore, various image print data generated by the personal computer 2 can be transmitted to the laser printer 3. [0003] The data received by the printer may be: 1) a string o...
