ABSTRACT:
A method of preparing a document for printing may include determining a preferred image resolution for an image on a document. An electronic file may be received. The electronic file may comprise data representing a first embedded image having a nominal resolution. A job may be received. The job may comprise one or more operations to be performed on the electronic file. A computing device may determine an effective resolution for the first embedded image based on the nominal resolution and the one or more operations. It is determined whether the effective resolution for the first embedded image is greater than the preferred image resolution. The first embedded image may be downsampled based on a scaling factor. A printing device may process the job using the downsampled first embedded image.
