Partial Font Downloading LaserWriter 8.6 supports the ability to download partial fonts containing only the glyphs used within a document. It is currently provided for TrueType fonts only. Other font formats may be supported in the future, depending upon OFA scalers that are made available. Partial font support is only provided for pure QuickDraw applications. Applications that create their own PostScript will not take advantage of this capability until they are modified.
Partial font downloading occurs only when background printing is enabled.
LaserWriter 8 subsets the font when it prints instead of using incremental font downloading. This feature allows documents of supported formats to be directly printed without launching the application that created them. This capability is an important feature which we have improved. In LaserWriter 8.6, when downloading a DSC conformant PostScript or EPS file, the new PostScript downloader will supply fonts used but not included in the document or available in the printer. In the future, other document types may be supported.
