Managed Printer pref's in WM not being applied correctly.

Question

I'm having real troubles trying to manage printers on our network using Workgroup Manager.
What I'd like to do is to be able to manage all users and computers list of available printers, so we can manage print volumes better and reduce problems with people not having access to the correct printer.
I know this is achievable using Workgroup Manager, and I believe I've set it all up correctly, however, it's simply not working.
Here's what I've done:
Added necessary printers to the Server using Sys Prefs on server. (Checked the printers by sending test prints from server)
Started Print Service on server using Server Admin, and setup queue's for each printer using IPP.
Made changes to User Preferences in Workgroup Manager to 'Always' manage Printing Prefernces, and added the relevant printers from the available list into the Printer List for each user/group.
I've duplicated these settings for the Computers aswell, to double check.
I've checked on user's logged into machines, and from System Profiler have confirmed that the relevant Managed Settings have been picked up by the client,
BUT...
When user's try to print, the managed printers I allocate them in WM, DO NOT appear in the list of available printers within any application, and in Sys Prefs / Print & Fax NO printers are displayed.
If I manually go in and manage Printers, I can add the printers which are shared by the Server and they work OK, but the whole point is that I want to manage the settings from WM, across large groups etc.
All other settings managed by WM (user dock settings, home folder mounts etc.) DO appear to be working, just not the Printing ones.
Please help!

Hi,
Well, that makes sense, and I've followed your instructions aswell as possible, but infortunately, I can't find a PPD file for one of the main printers - the HP2600n. Even the PPD for the HP3600 didnt work (although I am using HP3600dn's)
This just seems ridiculous - both printers are new, and not exactly obscure, and yet one of the most fundamental reasons for using a server - sharing service such as printing, simply causes more trouble than it's worth.
I can't beleive Server 10.5 can't accomplish this relatively simple task without this much ******* around required.
Also - if I manage a large number of groups/users print preferences, I would have to manually edit the com.apple.mcxprinting.plist for EVERY user/group - it would almost be easier to just go around the client machines manually installing the printers!
Rubbish Apple - sort this out please!
