i installed the latest CUPS PostScript Driver for Windows (6.0) into
/usr/share/cups/drivers/:

$ ls -l /usr/share/cups/drivers/ 
-rw-r--r-- 1 root root   803 Jun  5 17:51 cups6.inf
-rw-r--r-- 1 root root    72 Jun  5 17:51 cups6.ini
-rw-r--r-- 1 root root 12568 Jun  5 17:51 cupsps6.dll
-rw-r--r-- 1 root root 13672 Jun  5 17:51 cupsui6.dll

however, after attempting to install this driver, cupsaddsmb goes into an
infinite loop:
$ cupsaddsmb -v -H smbhost -U smbadmin printer
Password for smbadmin required to access smbhost via SAMBA:
No Windows printer drivers are installed!
No Windows printer drivers are installed!
No Windows printer drivers are installed!
No Windows printer drivers are installed!
.... goes on forever until i CTRL+C ...

running this through strace i see a pretty basic loop:
getuid()                                = 0
open("/var/spool/cups/tmp/4665db6e4c946", O_RDWR|O_CREAT|O_EXCL, 0600) = 6
fcntl(6, F_GETFD)                       = 0
fcntl(6, F_SETFD, FD_CLOEXEC)           = 0
write(6, "username = smbadmin\npassword = ."..., 34) = 34
close(6)                                = 0
access("/usr/share/cups/drivers/pscript5.dll", F_OK) = -1 ENOENT (No such
file or directory)
access("/usr/share/cups/drivers/ADOBEPS4.DRV", F_OK) = -1 ENOENT (No such
file or directory)
write(2, "No Windows printer drivers are i"..., 42) = 42
getuid()                                = 0
open("/var/spool/cups/tmp/4665db6e4cbe5", O_RDWR|O_CREAT|O_EXCL, 0600) = 6
fcntl(6, F_GETFD)                       = 0
fcntl(6, F_SETFD, FD_CLOEXEC)           = 0
write(6, "username = smbadmin\npassword = ."..., 34) = 34
close(6)                                = 0
access("/usr/share/cups/drivers/pscript5.dll", F_OK) = -1 ENOENT (No such
file or directory)
access("/usr/share/cups/drivers/ADOBEPS4.DRV", F_OK) = -1 ENOENT (No such
file or directory)
write(2, "No Windows printer drivers are i"..., 42) = 42

once i obtained the adobe postscript drivers (ps5ui.dll pscript.hlp
pscript.ntf pscript5.dll), the process ran quickly, registered the
drivers, and things seem to work ok now (i can print to the machine from
Windows at least and drivers are installed automatically)
