[Samba] 64 bit windows 7 printer drivers

[Joe]

Running samba 3.5.4 on FreeBSD 5.2.1 using lpr for printing.  I have printing
set up and working fine for 32 bit xp clients.  They connect to the printer
and the driver loads automatically.  I have uploaded the "HP Universal Printer
Driver" for a printer using the method described at the bottom of this bug...

https://bugzilla.samba.org/show_bug.cgi?id=6888

This goes ok.  When connecting to the printer the system complains it cannot
find a suitable driver however.  I suspect that samba does not know how to
associate this certain driver with this particular printer since of the method
used to upload it.  What can I do to associate the drivers with the printer?
