HELP: samba print setup

[x]

hi, all

  my system: redhat v6.0 samba 2.03

  my lan:  DOS (A) <------> Linux samba server (B) <------> Win95(C)

     C: setup printer share name --> W95_lp         ( MS Client v3.0 )

     B: setup SMB/Windows/NT Printer ---> lp0 --> \\C\W95_lp

        /etc/smb.conf

           load printers = yes

     A: setup printer port:  NET USE LPT1 \\B\lp0


Q.
     When Win95(C) is down, DOS(A) send to command: type file > prn,

I'm using NET PRINT \\B\lp0 at once, find print job in print queue \\B\lp0 ,

but again browse, find print task  is loss, Why?

Thanks
