glitch when printing from Win 7

[zeb7k]

When in Windows 7 I often use the print-region command from EMACS (23.2.1) to 
send text to the printer.  My lpr-command is the name of simple .bat file I use 
which simply accepts the temp file name that EMACS passes it and tells 
NotePad.exe to print it.

Well, under conditions I cannot fathom, the name that EMACS passes has some 
weird escape character at its beginning.  This happens about 5% of the times I 
try to print.  Once it does happen, it happens consistently.   I end up having 
to print manually: running NotePad, yanking from EMACS, pasting into NotePad 
and printing from the NotePad menu.   The next day, the problem is gone.  Kind 
of annoying.  Any ideas?
