This port has a modified filter "filter780.rev" which is useful to
print out more than one page. Then you execute the next command:

/usr/local/libexec/pips780/setup

to setup /etc/printcap, make a spool in /var/spool/lpd/ and so on.

To run with Japanese messages, you have to execute as follows:
 env LANG=ja_JP pips780
