I cannot install a printerdriver " Check that the Driver Store (idsd) is loaded"

It is loaded and active.
idsd.log : Apr 14 13:55:55 WARNING unable to write extracted file.
Apr 14 13:55:55 INFO ProcessEndDriverDataReq: Invocation of AddResource() failed with error 1280

What is the exact place where to upload the drivers on SLES 10 sp3 OES2 server.
So I can choose add from system ?
