printto is a fairly complex 30-line sub which prints to a filehandle. To use print's default behavior, I would have to duplicate that entire sub, changing print $fh ... to just print .... I want to avoid doing that; it would require any changes to the output routines to happen identically in both places to avoid inconsistency, and my experience is that this is error-prone.

Of course, if anybody has suggestions for another way to do this, I'm all ears!
