RE: IPDS to AFP (was Re: Confused about printing)

Charles--

I -know- that AFPDS does not require IPDS hardware in order to work. 
We have lots of HP and Xerox printers, without IPDS hardware, that 
correctly handle AFPDS data and print the appropriate graphics.

Both should be all-points addressable, but without IPDS the entire 
bit map is sent per page; IPDS separates the overlay from the 
variable data to make things run faster.  Unless it changed from when 
we set it up...
