Technically yes, In fact lost of programs can display and print PostScript. Apple Preview, PhotoShop, Illustrator, InDesign, and Quark all have the capability of displaying PostScript files and writing out to PDF. All these actions require that vector data be turned into raster data. Where most of these programs differ from traditional RIP’s is that they will not create halftone dots or individually control a printer ink channels (although all RIP’s do not do this). RIP’s are often used for workflow nowadays as the requirement for PostScript is becoming less necessary since customers can print and display PostScript in their applications. ImageNest will print and display PDF, EPS, and most PostScript formats.
