An electronic book, having a single screen, employs an electric field addressable, rewritable, colorant, preferably a bistable molecular colorant, for providing printed pages sequentially to a reader. The electronic book includes the rewritable screen coupled to an extraction-retraction device, an electrode array printer, a sheet position detector, and associated circuitry to download, store, sequence, and print images on the screen. Methods associated with document distribution are another aspect of the invention.
