OK,

I took the login part out of the equation and set permissions on the
share to allow Full Control to Everyone on that folder.

This is what the sequence looks like now.

Client: NBSS Session request
Server: NBSS Positive session response
Client: SMB Negotiate Protocol Request.
Requested Dialects
    Dialect: PC NETWORK PROGRAM 1.0
    Dialect: MICROSOFT NETWORKS 1.03
    Dialect: MICROSOFT NETWORKS 3.0
    Dialect: LANMAN1.0
    Dialect: LM1.2X002
    Dialect: DOS LANMAN2.1
    Dialect: Samba
    Dialect: NT LANMAN 1.0
    Dialect: NT LM 0.12
Server: SMB Negotiate Protocol Response
Capabilities: 0x0080f3fc, Unicode, Large Files, NT SMBs, RPC Remote
APIs, NT Status Codes, Level 2 Oplocks, Lock and Read, NT Find, Dfs,
Infolevel Passthru, Large ReadX, Large WriteX, UNIX

It seems the printer doesn't like the response because it closes the
connection with TCP [FIN, ACK]

Any insight on why the requested dialects and the corresponding
response would cause the printer to error?
