[Samba] printing to a Mac from Windows does not work

[robert b]

I am able to connect to my printer connected to my Mac (OSX 10.4.6) from both the Mac itself and from a Linux machine:

$ smbclient "//MINI/HP LaserJet 5L"

But, when I try to test printing, I get an error:

$ smbclient "//MINI/HP LaserJet 5L"
Password:
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.10]
smb: \> print test.txt
Error writing file: NT_STATUS_FILE_LOCK_CONFLICT
putting file test.txt as test.txt (0.0 kb/s) (average 0.0 kb/s)

Also, for some reason, after connecting, it seems that I am browsing /tmp:

smb: \> dir

I have precisely the same behavior when connecting from my Windows 98-SE
machine -- I am not able to print.

My printers entry in smb.conf is simple:

[printers]
        path = /tmp
        guest ok = Yes
        printable = Yes
        browseable = no

Any ideas what might be going wrong?

Thanks for any help.
