Imagen IP/II Image Processor 120VAC 50/60Hz 3.0A 360W Serial Terminal Engine

Imagen IP/II Image Processor 120VAC 50/60Hz 3.0A 360W Serial Terminal Engine

The Imagen IP/II is a desktop image processor unit manufactured by Imagen Corp of Santa Clara, California. It served as a raster image processing controller designed to drive laser print engines, translating document data from host computers into the high-resolution bitmap output required by laser printing systems. The IP/II communicates with host systems and terminals via dedicated rear-panel interfaces and connects directly to a compatible print engine.

Applications

Imagen Corp was an early pioneer in laser printing technology during the 1980s, producing raster image processor (RIP) controllers and laser print engines for workstation and minicomputer environments. The IP/II was used in conjunction with Imagen's own laser print engines and was commonly connected to Unix workstations, VAX/VMS systems, and other host computers of the era via serial or network interfaces. It translates page description data into raster bitmaps for high-resolution laser output, filling a role similar to what PostScript-based controllers would later standardize across the industry. These units were typically found in engineering, technical publishing, and university computing environments during the mid-to-late 1980s, where high-quality document output was required before desktop PostScript printing became ubiquitous. Collectors and vintage computing enthusiasts working to restore or operate period-correct Imagen printing systems remain the primary audience for units like this today.
