The first thing I do is to test the driver on a remote
Windows print server after unchecking the 'enable advanced
print features' box.  This force the printer to use RAW
printing only.  I've found that some drivers only work
with EMF printing.

Other than that it gets pretty hard to definitely determine
a driver bug in the registry data.  Basically comes down
to comparing bits in the PrinterData registry values between
a Samba printer and a local printer object using the same
