lpr is a Windows feature that you may be able to enable. It's under
"Print and Document Services" -> "LPR Port Monitor". It only installs
a 64-bit build, which is why loial is having trouble running it from
32-bit Python. But in Windows 7+ (Server 2008 R2), a 32-bit process
can use the virtual "%SystemRoot%\SysNative" directory to access files
in the native System32 directory. I can run lpr.exe from 32-bit Python
using this method.
