Disclosed herein are methods and systems for improving print quality. In one embodiment, a method of optimizing printer output quality is provided which includes identifying media in at least one media tray, querying a media database for a record corresponding to the identified media, extracting data from a record of identified media, adjusting printer operation based upon the extracted data, and printing on the identified media, wherein the printer operation is adjusted on a page-by-page basis within a single print job. Typical parameters which are adjusted during the print job are the transfer voltages and the volume of toner deposition. In another embodiment, media is assigned to groups based upon its color and print parameters are adjusted as different colors of media are used.
