Dear Sir.

Due to my bad English I will try to explain what kind of malfunktion I discovered
in the newest magicfilter 1.2 stuff. Prior to this malfunktion, I used magicfilter
in the desired way - fully functioning!

Base system is a FreeBSD 5.2-RC box acting as printserver for a couple of HP
network attached printers. Most of them are real PostScript printers with
Duplex facility and some colour printers have more than one paper tray which need
to be selected individually due to some transparencies inside some trays.

Here my specific problem.

I compiled ghostscript-gnu 7.07 from the ports and all the necessary stuff. I
also compiled a2ps-a4, psutils-a4 and magicfilter 1.2 as it is in the most recent

My intention is to have one line for each PostScript printer which sets specific
PS parameters for each print queue, for example select tray 2 for transparencies or
coloured plain papers or select whether the document should be printed duplexed or
simplex (several scientific reports need to be printed simplex, others duplex).

For this reason I wrote a magicfilter-filter file with this entry:

------------ example ----------
# lj4600-00-05-162-auto-s-filter

0 %!            filter /usr/local/bin/psset -q 
0 \004%!        filter /usr/local/bin/psset -q 

for automatic tray selection, simplex print.

Another filter file shows

------------ example ----------
# lj4600-00-05-162-auto-d-filter

0 %!            filter /usr/local/bin/psset -q 
0 \004%!        filter /usr/local/bin/psset -q 

the same for duplex. I have three more with the --setpagedevice=MediaPosition:XX otion 
set to select the
tray. This works with original PS-documents great! And I confirm: with PS documents I 
can do everything
I want!

So, now I need to print PDF and plain ASCII and I did this before on FreeBSD 4.8 boxes 
with magicfilter 1.1
by adding a line at the end like this:

0 %PDF          fpipe         `/usr/local/bin/pdf2ps  $FILE - 2>/dev/null`

for converting PDF to PS files an reinject the output into the magicfilter to be 
regarding to the PS-tags above (simplex, duplex, tray select and so on).

Another in the past working tag for plain ASCII conversion was this line:

default   pipe    /usr/local/bin/a2ps -q -R --columns=1 -B -j --ppd -k 
--prologue=color -o -

(on a colour printer system).

I got output with borderlines and appropriate to the PS-tags above I could print 
duplex or simplex or
selective trays.

And this does not work anymore!

Every printer I examinded (HP LJ4000, LJ4100DTN, CLJ4500, 2x CLJ4600DTN, LJ III, 
LJ1100) I realized,
that the printed file was piped into the print queue as is, unconversted, unprocessed!

I reduced several magicfilter filter files up to four lines, the two for PostScript, 
one for PDF and
the last 'default' for conversion with a2ps to print stupdi ASCII plain text as PS 

At last I will report, that I first used a working environment (printer setup, queue 
setup, magicfilter
setup, then I upgraded to FreeBSD 5.1 and the new magic filter stuff and since then 
nothing worked
as expected.
Another point seems to be that magicfilter isn't capable to inherit the ENVIRONMENT, 
so /usr/local/bin
is completely unknown if some filters like 'fixps' are needed. magicfilter should 
incorporate this
path, otherwise we need to link each needed program to /usr/bin and that's stupid 

It would be nice if someone has some solutions out here.

By the way:

This works fine on stupid non-PS printers:

--------- HP DJ 1120C A3 format printer ------------
# dj1120-00-05-273-auto-s-filter

# PostScript
0 %! filter /usr/local/bin/gs -q -dSAFER -dNOPAUSE -r300 -sDEVICE=cdj550 
-sOutputFile=- -
0 \004%! filter /usr/local/bin/gs -q -dSAFER -dNOPAUSE -r300 -sDEVICE=cdj550 
-sOutputFile=- -

# Acrobat PDF
0 %PDF          ffilter /usr/local/bin/gs -q -dSAFER -dNOPAUSE -r300 -sPAPERSIZE=a3 
-sDEVICE=cdj550 -sOutputFile=-
$FILE -c


hope this helps. Many thanks for staying up to the end of my report and have patience.
