Got it! Couldn't find the book I have it in, but a listing of the author's stories revealed it.

I was thinking Kuttner at first, but that turned up nothing. I knew it was someone from that era, someone who had written more than one story about enchanted Linotype machines. I finally dredged Fredric Brown out of the sludge I call a brain, and turned up... "The Angelic Angleworm."

I hate my brain sometimes.
