Help with smbprint.sysv

[Dr. Guilherme Regis]

Hi,

Does anyone happen to know a good document 
about SMBPRINT.SYSV ?
I am trying to make my SGi IRIX 6.2 print
to a PC Printer via SMB, unsucessfully.
I followed the smbprint and lp (sysv) docs
in Samba 2.0.7 but, I guess, something
is missing, I can not print to that
remote printer.
I think I do not need a printcap file since
it is using lp. But nothing happens and 
I get e-mail from spooler: error code 1.

TIA,
  Luiz
