Bob, i made a boad yesterday from 12 to 1 in the night, 2-sided
smd/throughhole, both sides component legend, ground planes, about the
hardest you can get with tt.

Even not couning all the wait time for the plotter i don't believe you can
best the time or effort or lack of concentration tt requires once you are
familiar with it.

I don't say it's impossible, just that it didn't work out for me.

By the way - pre-heating the paper worked like a charm to eliminate all
visible distortion/shrinking problems. I just run the paper through the
fuser first.
