I've _never_ been clear on this issue.

If nothing else, an element of IPDS that I haven't seen outside of 
IPDS is the ability of the printers to inform the system of printing 
status. Spooled files could be sent to 'intelligent' printers to be 
printed when the printer has completed previous print jobs; the 
files might be 'queued' inside the printer. The notification that 
printing completed wouldn't appear for the user until that spooled 
file physically finished printing.

I've often felt that the 'intelligent' communication between printer 
and system was a kind of defining characteristic of IPDS regardless 
of AFPDS content.

But there seems to be so little clear info on both terms...
