Hmmmm.  Where (on Windows 8.1) is this 'lpr' command (or where is it
supposed to be)?  What exactly is it used for?  How is it used?

I think I found it in a hidden temp directory, but I don't have any
clues on how it is used.

I had thoughts along this line too (missing formfeed at end of file?),
but haven't devised a test yet.  Thought I might try the Windows 'lpr'
you spoke of to see if it worked better.  The 'print' command seems to
work, but I'm not sure if it has conversion problems (CRLF -> LF or vice
versa) and, so, causes strange wraps in the output.  If it had more
output controls, I'd probably just settle for that.
