samba - Mar 2012 - Printer Connection Problem

I have about 10 printers installed through cups (all working via test 
page printing via cups webpage). Roughly half of these are experiencing 
this problem with samba.

When I run

[root at pluto ~]# rpcclient localhost -U'root%j3yThEiH' -c
"enumprinters"
         flags:[0x800000]
         name:[\\LOCALHOST\]
         description:[\\LOCALHOST\,,HP Laserjet8000DN]
         comment:[HP Laserjet8000DN]

         flags:[0x800000]
         name:[\\LOCALHOST\e9hp3015]
         description:[\\LOCALHOST\e9hp3015,,HP laserjet 3015]
         comment:[HP laserjet 3015]

-- truncated

half of them are missing the queue name part in the name field...

And when I try to connect to these from windows I get

Connect to Printer. Windows couldn't connect to the printer. Check the 
printer name and try again. If this is a network printer, make sure that 
the printer is turned on, and that the printer address is correct.
