Abstract: Example methods and systems to implement an economic printing mode with font information modification are described. In one example, a computer system may obtain source printing content associated with a print job that is destined for a printer and the economic printing mode may be selected for the print job. The computer system may extract, from the source printing content, (a) textual information to be printed and (b) font information associated with the textual information. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content by modifying the font information associated with the textual information. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.

Abstract: Example methods and systems for printing ink consumption estimation are described. In one example, a computer system may obtain printing content associated with a document that is printable using a printer. Based on the printing content, the computer system may generate an image representation of the document, wherein the image representation includes an array of multiple pixels associated with first color information from a first color space. Color conversion may be performed by converting (a) the first color information from the first color space to (b) second color information from a second color space associated with the printer. The computer system may estimate an amount of printing ink required for printing the document based on the second color information and provide the estimated amount of printing ink to a user via a user interface.
