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

Didn't I read somewhere that IBM has or was dropping support for IPDS?

IPDS is designed to work with form overlays.  The protocol will
transmit the overlay to the printer, which caches the overlay.  Then
the variable data is sent, page by page, to the printer.  If I
remember what I read correctly, the printer can cache several
overlays to save even more time.

AFP can't handle the caching--  you can print the same things that
IPDS prints, but the iSeries has to build a bit map of every page and
send it to the printer.  On a local connection it isn't too bad.  But
on a remote connection, you'll clog your comm link!

The variable data that IPDS sends for each page is only a few
characters-- a full 80 x 24 green screen is about 1920 characters;
the bit map is a whole lot larger.
