[Samba] samba 2.2.9: printing problem II

[kurt weiss]

sorry, if i post again, but at first time i did not get an answer :-(

problem:
when printing from windows clients to samba 2.2.9 PDC, there are strange 
entries in the smbd logfile:
e.g.:
smbd/service.c:make_connection(252) notebook01 (192.168.10.29) could'nt 
find service lpb8-a4-ra

the strange thing is, that the service is names "lpb8-a4-raw".

also the same with the other printers:
service "hpusb" -> "hpus"
service "pdfplotter" -> "pdfplotte"
service "pdfprinter" -> "pdfprinte"

can somebody tell me the reason, because i have heavy troubles with one 
of the printers, and i cannot locate the problem (wixp or samba).

samba is reading the services from etc/printcap.
debian woody / samba from source tarball / SMP server / kernel 2.4.19.
