Method to reduce printer ink consumption leveraging on the font choice

     In some situations, it is useful to reduce the amount of ink needed by any printer to print a document; this could happen when the printed document layout is not important (e.g.: a personal draft copy) or when the amount of ink available for printing is small and it is needed to successfully print the document. More generally, it is desirable to reduce ink consumption for "green" purposes to limit pollution which can result from ink wasting in document printing actions. On the other hand,

which lies on a reduction of the ink density per area

that is to use less ink to print a particular area. This approach is often correct and can effectively reduce the ink consumption to print a document. However, such approach consisting in reducing ink density per area can affect the document readability because using less ink can be prejudicial to the integrity of the printed content, due for example to some confusion related to the document background or to another printed element.

     The proposed solution relies on a different approach for optimizing ink consumption during the printing operation for any given document. It results in a final printed document accessibility in terms of readability that can be granted, even if finally less ink is needed to print the document, despite a standard printing mode.

     The core idea of this solution is to provide a method inside any document editor application that selects an appropriate font style for a given electronically document that needs to be printed, so that the amount of ink needed by any given printer, to print the document, is minimized, despite the originally font style associated with the document.

     The method comprises the following steps:
- it receives any electronically document to be printed as input;
- it receives a set of font styles (so that it would be acceptable for the user to get the document printed using any font style belonging to the set)

     - it computes the font style in the input set of font styles that minimizes the ink required for printing;

- it orders the set of font styles by growing ink required for printing;

     The method then:
- provides the user with the font style that minimizes the ink needed for printing, and a preview of the document converted to that font style

     - asks the user if he/she wants to print the document with the new font style (

with an estimate saving ink percentage value

     - prints the document if the user accepts the previous request, or return to previous step if the user does not want the proposed font style.

Several methods can be used to compute the font styles so as to minimize ink
