Print, Frosty?

bogus% lpr -P ps2 filename

Scan?

bogus% scanimage -d hp:/dev/sg0 --mode grayscale > filename

Hm, I knew there was a reason I liked Linux. :-)

ObSmithing: 

Finally got a compressor going. A 400 PSI 2-stage compressor, 60
gal. 600 PSI Halon tank, 2HP motor, basket of switches, valves, hose
etc. from Princess Auto. Total cost about C$500.  Gets up to 150 PSI
from 0 in a few minutes.  I won't have a way to evaluate CFM until I
disassemble the plumbing, move it from the middle of the floor to its
permanent location and seal up all the pipe thread leaks.  Might have
to spring for a 5HP motor to run a big hand-held air hammer but it has
enough CFM for most stuff as it is.

I had great fun working with a hand-held air hammer on a visit to
David Court's shop.  Work up details on the end of 2" round in half
the heats it takes doing it by hand.  Of course, there's the time to
re-make all dem t'ousands of tools with special shanks to fit the
hammer.  Or maybe just a couple-three nearly-all-purpose
holders/adapters for existing tools?  We'll see, real soon now.
