HP PPL Command Reference Documentation

[MikeSD]

Why is there no Command Reference Manual for HP PPL? Seems odd. I've seen people asking for the location. And I've searched. But it seems more like this is tribal knowledge.

I have found a bare list, and I have found tutorials, but is there any Command Reference for HP PPL, other than what's in the Owner's Manual? I guess I'm just used to seeing a language documented in it's own manual. Maybe it's not necessary, in this case.
