Pipe the contents of the current node through the command in the
environment variable INFO_PRINT_COMMAND
. If the variable does not
exist, the node is simply piped to lpr
(on DOS/Windows, the
default is to print the node to the local printer device, PRN).
The value of INFO_PRINT_COMMAND
may begin with the ‘>’
character, as in ‘>/dev/printer’, in which case Info treats the
rest as the name of a file or a device. Instead of piping to a command,
Info opens the file, writes the node contents, and closes the file,
under the assumption that text written to that file will be printed by
the underlying OS.
