As an aside-- I really do dislike cups.

Anyway the problems.

I have a variety of computers on a subnet x.x.x.10 to x.x.x.50 as IP
addresses. I do not my printer being available to everyone on the x.x.x
subnet. But I cannot figure out any way of limiting it to the above without
listing every single machine in the Allow lines.
I tried x.x.x.0/27 but that did not work. I tried x.x.x.0/255.255.255.63
(both should allow everything from 0 to 63 I know, but it is better than
nothing)

but again no go. Does anyone have a way of listing the files in a range
without listing every file in that range.
As far as I know there is no way of designating a range-- or is there?

b) I want certain printer to be the default printer. Cups lists a default
printer, but there seems no way of listing one default under the cups
(localhost:631) administration web stuff. And while cups lists one printer
as the default, the actual default ( ie the printer that stuff is sent to
with lpr) is different.

b') Where does cups store its info. I get 10 printers listed as being
available, /etc/printcap contains lines for them, but
/etc/cups/printers.conf is empty. (this is on a remote computer, which has
no attached printers).

c) When I try clicking on "modify a printer" it leads me through a whole
list with no defaults. While maybe OK for some things, when I see the
option
socket
staring at me with no clue as to which of the 10 options is the correct
one, and no way of finding anything in any documentation to tell me, I can
only give up. That is just silly. Give the bloody default so I can change
it if I want, instead of having to know everything to do anything.

d) On remote printers the margins are not preserved. I have to put the
margins explicitly into lpoptios on the remote computer for them to work.
 (I have the proper margins on the print server, but somehow stuff coming
 from a remote compter ignores those-- why? And there seems no way of doing
this- setting margins-- from the cups admin web pages. )

e) On Mandrake, the options lpr and lpq are supposed to work, but they do
not. Thus I send a job to the printer and type lpq and there is no
indication that anything is there. If I type lpstat, I suddenly see stuff
in teh queue. What is lpq and lpr for? Do I have to tell all my users not
to use lpr and lpq anymore? Or point them at lp and lpstat? Why are they
there but not working. ( Mandrake 10 specifically this refers to.)

argh, I hate cups.
