Thanks.  I think the printer can do better, though.  It's very
sensitive to the paper you print on.  For example, printing on a
transparency gave very crisp edges, *but* there were drop-outs due to
dirt on the transparency, and my attempts to clean it only made the
results worse.  I'm using Pulsar's paper at the moment, when that runs
out I might try press-n-peel to see if my printers like it better.  I
also haven't tried adding Pulsar's green film with the HCl bath; these
results were with just toner.

I do still recommend rehydrating any paper you print on, it seems to
consistently help.

I'm also looking forward to experimenting with the photofilm I got;
maybe that will produce a more reliable edge.

The other thing I haven't figured out is how to get my color laser
printer to overlap all its toners to get a really thick coating.  It
seems to ignore the relevent commands I send it and do what it thinks
is right :-(
