Source is usually regarded as the origional human-readable stuff to control a logic statemachine. (Usually a computer in todays jargon). If you mean the source to the actual micro-processor inside the PaintJet, then you will not be able to get this; this is the property of HP, having engineered the PaintJet. This source is responsible for collecting data from the outside world (ie you and I), interpreting it, then running the assorted control motors (paper feed, carriage control etc) and the ink jet assemblies. If on the other hand you are referring to the "command language" used to drive the printer (ie the assorted escape sequences), so you can dump images, do bold, underline, color control etc etc, then HP publishes a programming manual that tells you how to do this. Call HP DMK (they have an 1-800 number), and they will be able to tell you the appropriate manual, plus cost. It's actually pretty easy; there are only about 30 or so esacpe sequences, and it is not too difficult to program these (you should find nroff -man will get most of the simple ones OK for text, if TERM is set to "hp").
