Yes, that's intended. The host with the printer is supposed to do all
the filtering.

Well, you have to make some host do the filtering. This host then has to
"simulate" a local printer. In my printer scripts this is simple to do
as I can chose a shell script that sends the data to the printer. I have
scripts that send data to stdout (i.e. a local tty port), an Emulex
printer server, NCD X-Terminals with printer port or any TCP port (I use
this with a HPLJ 4 with Ethernet card and send the data to port 9100).

Well. The printer system always thinks in terms of queues. If you want
to manage multiple printers with a single queue then you could make the
filter program do that. I haven't seen such a filter though.
