Adobe defines Postscript Level 3 as having three enhancements: Enhanced Image Technology, Advanced Page Processing and Planet Ready Printing. The LaserWriter 8500 supports the core features of Postscript Level 3. The printer does not support what are defined as optional Postscript Level 3 features, nor does Apple have any current plans to support them in the future.
Supported by LW 8500:
Enhanced Image Technology
- Smooth Shading: renders gradient fills at resolution of the printer - improved half toning reduces banding and improves image output quality
Advanced Page Processing
- Faster imaging performance. This of course is just one part of the printing process, so total printing times may vary.
Planet Ready Printing
- Standard set of fonts for all PS3 printers
Unsupported by the LW 8500:
- Direct PDF Printing
- Direct HTML Printing
- Web-based management
