> How did you obtain the ml1610.service file which you have attached?
I wrote this file on my own based on the description at
http://blog.emeidi.com/2007/12/netzwerkdrucker-mit-avahi-anpreisen.html and
some details from
http://developer.apple.com/networking/bonjour/BonjourPrinting.pdf
(documentation on this topic is really sparse). The latter document hinted that
the "product" key should match the "Product" value in the PPD; but in
/usr/share/ppd/splix/samsung/ml1610.ppd I could only find these Product values:
*Product: "(ESP Ghostscript)"
*Product: "(GPL Ghostscript)"
*Product: "(GNU Ghostscript)"

Well I'm not in that network anymore so can't give _exact_ output (and
the print server is not available now); but after installing the
ml1610.service file on a local machine, here's the output from dnssd:
~$ /usr/lib/cups/backend/dnssd
network lpd://192.168.0.1/P1 "Samsung ML-1610" "Samsung ML-1610 192.168.0.1"
"MDL:Samsung ML-1610;DES:Samsung ML-1610;CLS:PRINTER;"

Aaaanyway... shame on me, because s-c-p did print some more info to
.xsession-errors as I noticed just now:
