Method of limiting amount of waste paper generated from printed documents
This invention details a method of providing a method of limiting the amount of waste paper created when printing documents. One of the main problems encountered by today's business environments is the generation of tons of waste paper. With the current trend in maintaining a “recycle minded” mentality, it would seem obvious that in preference to recycling used paper, what is needed is a process that limits a amount a waste paper in the first place.
1 . A paper saver comprising:
a computer processor for recognizing blank space in a page of a document to be printed, the processor being operative to cancel printing of the page if a percentage of the blank space exceeds a user selectable threshold.
2 . A method for saving paper in a printing environment comprising the steps of:
storing an image in memory;
identifying each line of the image based upon a percentage of blank space;
determining a percentage of blank space on each page based upon the identifying step; comparing the percentage to a threshold; and
preventing printing of the respective page if the percentage is above the threshold.
3 . A method as recited in claim 2 , further comprising the step of disabling the method by a user.
4 . A method for saving paper comprising the steps of:
defining a grid for a last page of document to be printed, the grid having a plurality of pixels;
determining a subset of the plurality of pixels to be printed upon;
determining a page ratio between the subset and the plurality;
selecting a ratio threshold; and
determining to print the last page based upon a comparison of the page ratio to the ratio threshold.
