The present invention relates to a method and system for efficient image handling. The invention includes an image server with which image files are registered. The image processing requests are sent to the image server to produce image data representing the processed image file. In one embodiment of the invention, a document processing application obtains an image file for printing. The application registers the image with the image server. The image server returns an identifier identifying the image file which is used for subsequent image processing requests. The application initiates a print job, sending the image identifier and selected print parameters to a printer driver. In response, the printer driver negotiates image processing requests with the image server to modify the image file in accordance with the selected print parameters. Finally, the processed image data is retrieved from the image server and sent to the printer. The image server and printer driver may be separate and independently executing processes. In an alternate embodiment, the application, image server and printer driver are loaded on two or more networked computers.

Method and apparatus for processing and printing documents

In a color printer system, an interactive user interface allows a choice between one-'button' automatic control of color output or multibutton control of color output, with both automatic and manual options providing independent control for color halftoning and for color correction based on the types of objects to be printed. The preferred form allows independent print-rendering options for text, graphics and photo images.
