OK.... I'm resorting to one of my least favorite pastimes - replying to myself, but maybe it will help someone else.
So it looks like the only "easy" way for me to print in Shockwave is to use the PrintOMatic xtra. I have not gotten it to work yet (connection problems with the PrintOMatic download site?), but I'm writing this in the hopes that a 2nd post here will attract some attention and maybe an alternative print method will surface.
Thank you so much!! The Flash Asset xtra does indeed allow for printing in Shockwave!
For someone (like me) without much understanding of object oriented programing (i.e. class, instance, ancestor etc.), it takes a while to get a sense for how it works, but ultimately it can be cut, pasted and cobbled together to suit one's needs.
