[Samba] Samba Printing api_rpcTNP: \spoolss: SPOOLSS_OPENPRINTEREX failed

[Achim Gottinger]

After an day without issues i just received an phone call about an 
printing issue and i found a few "illegal multibyte sequence" errors in 
the log file again.
Unfortunately i can not reproduce the situation where this error occured 
an second try to print that document out of the archive worked but since 
it's an crystal report form generated out of an database from our 
business software something may be different when printing from the 
archive. Hope i'll get an reproducible situation so i can grab an 
wireshark trace and more detailed samba log info's.
