[Samba] samba 2.2.9 - strange printing problem

[kurt weiss]

we're using samba 2.2.9 as PDC. (w2k/wxp as clients)
following strange lines i found in smbd.log:

... smbd/service.c:make_connection(252) notebook01 (192.168.10.29) 
could'nt find service lpb8-a4-ra

the strange thing is:
the service is named "lpb8-a4-raw"
also the same with the other printers:
service "hpusb" -> "hpus"
service "pdfplotter" -> "pdfplotte"
service "pdfprinter" -> "pdfprinte"

samba is reading the services from etc/printcap.

etc/printcap:
