Release Notes for pnm2ppa-1.0  July 11, 2000
---------------------------------------------

This release is the 1.0 release of pnm2ppa.   It is fully functional
on all three PPA printer families, and has no known bugs. (Is "Flashing
LED syndrome a thing of the past?)

It can now handle all paper sizes compatible with the printer, and all pnm
formats.

The documentation is updated.

----

Remaining issues such as somewhat-visible horizontal swath boundaries on 
uniform dithered color backgrounds (such as in the ghostscript example 
tiger.ps)  cannot be resolved without major design changes, but this should 
not affect most uses of pnm2ppa. (see the TODO file).  
Such changes will require significant effort (by someone highly motivated) 
to be achieved. pnm2ppa is probably as good as it can get by tweaking its 
code with little bug fixes.

Improvements in color correction techniques could still be achieved,
though (see docs/en/COLOR.txt).

Calibration and printer utility procedures (head cleaning codes, etc)
could also be added. (perhaps using the PUP utility?)

Use of data compression of sweep data for color sweeps could also be
added without a major rewite, to perhaps speed up printing.
