LaserWriter 4/600 PS

The LaserWriter 4/600 PS was a compact monochrome laser printer from the LaserWriter series that was released by Apple Computer for the home office market on June 19, 1995.

Description
The 4/600 PS could print at a resolution of 600-dpi from a Canon LBP-PX print engine that could output 4 pages-per-minute with a rated life of 100,000 pages. It is compatible with HP LaserJet 4ML toner cartridges. It utilized FinePrint and PhotoGrade to adjust individual dot sizes to simulate smoother edges and grays produced by higher resolution printers. Memory compression technology allows it to use less RAM while printing complex documents.

The 16 MHz AMD processor could rasterize images from PostScript Level 2 printer data. It only supported LocalTalk networking over its serial port. Despite the change in branding, the enclosure is the same as that used by latter Personal LaserWriter models.

Discontinuation
The 4/600 PS was the last compact laser printer from Apple, with the final model being the LaserWriter 8500 workgroup printer. A higher-output alternative was the LaserWriter Select 360.
