Abstract
In one aspect, a method and apparatus is provided for reducing ink consumption when printing electronic documents. An electronic document is processed to identify different elements of the document, such as images, text blocks, and advertisements. Once the element identification is complete, a score is assigned to each one of the elements. The scores are then compared against a threshold T and only elements whose scores exceed the threshold T are printed. By filtering out some of the elements of the electronic document, the method and apparatus conserves ink and other printer consumables.
