jpeg2ps converts JPEG files to PostScript Level 2 or 3 EPS. In fact, jpeg2ps is not really a converter but a "wrapper": it reads the image parameters (width, height, number of color components) in a JPEG file, writes the according EPS header and then copies the compressed JPEG data to the output file. Decompression is done by the PostScript interpreter (only PostScript Level 2 and 3 interpreters support JPEG compression and decompression). If you have a slow communication channel and a fast printer, sending compressed image data is a big win. WWW: http://www.pdflib.com/download/free-software/jpeg2ps/
