Workgroup print server

[as1981]

I'm running a print server in a workgroup environment and therefore users don't authenticate to the server individually. Which permissions do I need to allocate to the everyone group so that they can add printers, print and delete print jobs.

At the moment I've having a problem where I add a printer from the server and it says it's succesful but when I tried to access the properties of the printer from the client it asks me to install the driver.

Thanks
