I've made some estimates on a samba 2.2.4 on Solaris 2.6
and a NT machines looking up properties for a given printer and making
some changes to it.
Samba NT 4
100 2-3 finding properties
6 2 changing driver setup
numbers are seconds.
Looking at debug information I se a lot of ?

My printing setup is:
lpq cache time = 10
printcap name = lpstat
printing = sysv
print command = lp -c -d%p %s; rm %s
lpq command = lpstat -o%p
lprm command = cancel %p-%j
lppause command = lp -i %p-%j -H hold
lpresume command = lp -i %p-%j -H resume
