Fixed!

:-) Sigh... PLP will never die...

Hmmm... Now this is an interesting thought. The latest 'use unix socket'
fakes a 'localhost' IP address. I think that a 'better' form is:
ACCEPT SERVICE=X REMOTEIP=193.0.88.0/24,128.0.0.0/8
REJECT SERVICE=X
I will put a note in the lpd.perms file about this.
## # All operations allowed except those specifically forbidden
## DEFAULT ACCEPT
##
## # Accept connections from hosts on subnet 130.191.0.0 or
## # from the server.
## ACCEPT SERVICE=X REMOTEIP=130.191.0.0/255.255.0.0,\
## 128.0.0.0/8
## # from a named set of sites
## ACCEPT SERVICE=X REMOTEHOST=engpc*
## # listed in the /etc/accepthost file
## ACCEPT SERVICE=X REMOTEHOST=</etc/accepthost
## - /etc/rejecthost contains list of entries separated
## by whitespace. For example:
## 10.0.0.0/8 128.0.0.0/8
## 192.168.10.1 192.168.10.2
## # don't take them from this particular host
## REJECT SERVICE=X REMOTEHOST=badhost.eng.com
## # Reject all others
## REJECT SERVICE=X

Yes. You use the ':oh' entry:
.common:sd=/var/spool/lpd/%P:mx=0:...
# everybody sends to pr1
lp_on_pr1:.tc=.common
:[EMAIL PROTECTED]
:force_localhost@
# and on the pr1 host you now dump to printer
lp_on_pr1:oh=IP.ADDRESS.OF.PR1_HOST:
:lp=/dev/lp0
