The LaserWriter II NTX was considered by many to be the best laser printer available from any vendor. It held this top spot from the time it was introduced until QMS came out with the PS-810 turbo nearly two years later. The NTX was sold primarily to professional desktop publishers and service bureaus who needed a fast, true Adobe PostScript printer to proof pages that would eventually be printed by Linotronic image-setters equipped with Adobe PostScript RIPs. As a proofing device for the new high-end publishing systems, the LaserWriter II NTX was a key element in the revolution that converted the publishing world to PostScript and made many expensive proprietary typesetting systems obsolete. The magic combination of the reliable Canon SX engine, Adobe Systems software, a fast controller, and the ability to interface to a disk that could store the entire Adobe library of fonts on line... all this made the NTX a best-seller for years.
