Something like this (not tested) should work:

p1102:HP LaserJet P1102:sh:lp=/dev/ulpt0:sd=/var/spool/lpd/p1102:lf=/var/log/lpd:if=/opt/bin/filter-p1102

Then /opt/bin/filter-p1102 is where the printer filter resides.
In "my" nomenclature, /opt is for everything that is not managed
by the ports or by the system. Maybe you chose a better location,
e. g. /etc/filter-p1102 or /usr/local/filters/filter-p1102, just
as you like.

Also make sure the spool directory and the log file do exist.

The file filter-p1102 itself is just a shell script. It works as
a wrapper for your foo2<whatever> filter, foo2zjs in your case:

#!/bin/sh
export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin:/usr/local/sbin
/usr/local/bin/foo2zjs-wrapper <your options>

It reads from stdin and outputs to stdout, and this mechanism
is embedded in lpd's processing chain, as far as I understood.

True. Get rid of the CUPS monster and use the excellent system
tools to do this simple job.
