To procrastinate some things I had to do yesterday, I pulled the User's manual of the original HP DeskWriter out of my bookshelf. To my surprise, I realized that this printer can a) use AppleTalk networking, b) can autodetect the presence of LocalTalk dongles and automatically switch between serial and network communication and c) doesn't use ADSP for AppleTalk communication, but, like the LaserWriters, uses PAP. This last point really astonished me. Up to now, I thought non-PostScript AppleTalk printers just tunnel their serial communication protocol through ADSP (which, like TCP, allows UART-like communication over the network).
I now wonder if there are any (other?) documented uses of PAP with other protocols/languages than PostScript.. Or is the DeskWriter maybe really using PostScript for printing?
