Ummm.. Do you actually have a program called lpr.exe in that location?
It's not usual on Windows. (I rather assume you do since you give the
full path, but still...)

IOW, what happens if you type:

  dir C:\windows\system32\lpr.exe

at a command promopt?

Also: are you on a 64-bit system? If so, c:\windows\system32 probably
isn't where you think it is. cf, for example:
