Why 'scp' ? From a firewall box -- when I need to print, I pipe the
content toward my throwaway script 'remotelpr', type a password (in
this case, for oldnews.inside.lan), and it prints inside my lan.
This would be safe and onestep across the public internet as well.

[root at pokey bin]# cat remotelpr
#!/bin/sh
#
HOST="oldnews.inside.lan"
cat - | ssh $HOST lpr -
