[Samba] Clarifying CUPS Printing

[SMITH Gregory C.]

We have been using CUPS to handle printing and have run into some "features"
some of which a fresh install of the responsible server will probably fix.
However there are some disparities between the documentation and our
practical experience for which a clear statement would help others.

The docs state when using CUPS the relevent lines of SMB.CONF should look
like this:

printing=cups
printcap=cups

And that any manual printing command are ignored.  However, if we set
printcap = cups nothing happens and we cannot see any printers.

What we do have is the following:

printer admin = @DomainAdmins,root
load printers = yes
printing = cups
printcap= /etc/printcap
print command = lpr.cups -r -P%p -o raw %s
lpq command = lpstat -o %p
lprm command = cancel.cups %p-%j

See any problems with this?
