The stand-alone Info program expects the environment variable
INFO_PRINT_COMMAND to point to the name of a _program_ to which
Info will pipe the text of the node you want to print.  That
program should then send the piped text to a printer.  In other
words, you can set INFO_PRINT_COMMAND to be the name of any
program that can read text from its standard input and will write
it to a printer.  The default is lpr, but many PCs probably don't
have such a beast installed.  If you are one of those who don't
have lpr, or any other program which writes standard input to a
printer, then you can use any program which will write it's stdin
to stdout instead.  I use cat (from GNU Textutils, you can find it
in the GNUish directory on SimTel mirrors, if you don't have one).
I set the above environment variable thusly:

	set INFO_PRINT_COMMAND=cat

I then invoke Info like this:

	info > prn

(Info writes to the screen with direct screen I/O, so this redirection
doesn't affect what you see on-screen, but it has a side effect of
redirecting stdout of any child program Info invokes to the printer.)
Then I print any node with the ``M-x print-node'' command.  It really
works!
