In reply to an inquiry about DDL on the new Laserjet II:

DDL (Document Description Language) is Imagen's page description language,
similar to PostScript.  It differs from the Laserjet's native PCL (printer
command language) in that it is designed to support advanced graphics,
paper handling, and font generation.

Steve Jobs called HP's support of DDL (rather than Postscript, used by
Apple) a "brain damaged" decision; I believe at that time he owned several
million dollars worth of Apple stock.  HP apparently selected DDL for
its added capabilities such as support of both bitmapped and algorithmic
fonts, image caching, graphic image macro-ing, and binary as well as ASCII
command control, etc.  For more information, see product brochures for
HP's "Laserject Publisher Kit."
