Hi, because I did not receive any response at all to the above query,
I have started some experimenting myself. It turned out to be not as
hard as feared. Just in case someone is interested, the code below
adjusts for normal-res faxes, based on the file name:

{
        # optionally take data as new archive directory
        if [ ! -z "$data" ]
        then
                printer=$data
        fi
        for file in $*
        do
                res=`basename $file | cut -c4`
                if [ "$res" = "n" ]
                then
                        stretch="-s"
                else
                        stretch=""
                fi

                log "print $file to $printer"
                g32pbm $stretch $file \
                | pnmscale -xysize 2479 3508 \
                | pgmtopbm -fs \
                | pbmtolj -resolution 300 \
                | lpr -P $printer
        done
}
