here's a perl hack (out of my head, so you may have to fix any
syntax problems):


# put this in /etc/printcap instead of the normal magicfilter
# to catch before/after glimpses of what's happening

#change this to match the desired 'real' filter
$magicfilter = "/bin/true";

use IPC::Open2;

open LOG_PRE_FILTER, ">/tmp/filter.$$.before"
  or die "Can't open file: $!\n";

open LOG_POST_FILTER, ">/tmp/filter.$$.after"
  or die "Can't open file: $! \n";

open2(FROM_FILTER, TO_FILTER, $magicfilter) 
  or die "Error opening filter: $! \n";

# turn off buffering on our side of filter
$| = 1;

while ( defined(<STDIN> ))
  print TO_FILTER;

close TO_FILTER;

while ( defined(<FROM_FILTER>))
  print STDOUT;


--- cut

make sure this runs (from the command line) then put it in /etc/printcap.
Print something the normal way, then print something in WP, and compare the
resutling files in /tmp ( or shar them and mail them to me) and see what
is happening.
