Hi, Clifford.  This project had actually been started by several people
outside of HP.  I joined it on my own initiative as a side project on
my own time, because I recognized that there was an unmet need for this
level of support.  Gradually I have gotten more and more support from HP
management, to the point where this project is now an official part of my
job description.  I'm glad that this project has been well-received by many
people in the community, and I've certainly enjoyed being a part of it.

Scanning with SANE is not yet supported on this model, but it's on my TODO
list.  In the meantime, you can scan using the "ptal-hp" command-line
utility, which is available with the development code in CVS (not 0.7) and
will go into the next stable release (0.8, probably sometime in August).
For more information, see "http://hpoj.sourceforge.net/hpoj-cvs/SCAN-HOWTO",
but don't pay any attention to the part that talks about SANE.
