How can I set different printer configs for users on the same machine?

[Lifeboy]

I have a ppd file with some special settings for a postscript printer.
This is an OEM Kyocera printer, sold by Triumph-Adler (model DC-2240)

The printer is setup for user authentication via a pincode.  The ppd file contains the following lines:

*% Management Code Definitions
*OpenUI *KmManagment/Job Accounting: PickOne
*OrderDependency: 60 AnySetup *KmManagment
*DefaultKmManagment: MG00000002
*KmManagment Default/Off: ""
*KmManagment MG00000000/Appollis: "(5463) statusdict /setmanagementnumber get exec"
*KmManagment MG00000001/Wendy: "(7958) statusdict /setmanagementnumber get exec"
*KmManagment MG00000002/Rozanne: "(0986) statusdict /setmanagementnumber get exec"
*KmManagment MG00000003/Betsie: "(4621) statusdict /setmanagementnumber get exec"
<snip>

This results in a "Job Accounting:" option to be displayed in the cups web interface as well as the Ubuntu system | administration | printing setup.  In the dropdown box I can select the user I would want to print as and the printed pages get counted for that user.

However, here is the problem: When I change the job accounting user, the value gets changed for all users on the server.  Since this is a multi-user server (aren't all linux machines by default?!) this creates a huge problem.

I have searched the web using almost all conceivable questions, but there doesn't seem to be a single person that has ever had this requirement, something I find really hard to believe.  Everything seems to be machine centric, not user centric.

I see there is a file ~/.cups/lpadmin that contains:

Default TA_DC_2240 Duplex=None PageSize=A4

This allows one some form of control per user, ie, each user can have his/her own default printer, and some form of printer control.  However, there does not seem to be a specification of the options that can be added to this file.

What I'm looking for here is a way to place /etc/cups/cupsd.conf into ~/.cups/cups.conf and more still to have a personal ppd file place in this location.  This would allow each user to specify his/her own settings, without affection the rest of the users.

I know the windows world has had this all the time, but cups is much older and more mature, not so?

Is my thinking wrong, ie. should I approach this problem differently? I could create a printer for each user and only allow that user to access the printer, but in a way that's crazy: Having 15 printers for 15 user?  What if I have 500 users?! It may be a temporary workaround, but it's not a solution.

Thanks all for your consideration.
