Your script's problem is that it prints ONE escape code and then
exits.  I think that the effect is going to be not what you intended.
(It is possible that lpd is sending the rest of the printer data to
/dev/lp by default when the filter exits early...otherwise, I think
that it will just have to discard the data to be printed or hold it
in a queue.)

I ran across this same problem a while back.  It looks like I solved it
to a certain extent and then got pulled away.  I remember deciding that
I had all of the pieces, but it doesn't look like I ever got "line-
printing" to work.  (I mostly print via PostScript through GhostScript,
over a network, and into my trusty laser printer.)


I don't think that you need MagicFilter for this.  A filter script that
looks like this should be enough:

 /~~~ filter

#!/bin/sh

awk '{print $0 "\r"}'

 \___ filter

On my machine that directly attaches to the printer, this is what I do,
and it is sufficient.

I prefer to use a set of lpd/lpr layers with multiple printcap entries
rather than relying on some "magic" program to sit quietly in the data
stream and guess what what I want.

If I want "magic" to happen, I use "a2ps" to generate PostScript and
then have GhostScript render that down to my printer.
