With the new dcerpc architecture we need to keep printer-list.tdb around. A spoolss dcerpc call will start rpc-spoolssd which will then start the background queue process. However in order to enum the printers we need have a printer-list.tdb. Depending on the number of printers this task can take several seconds. It is unlinkly that the printer-list will change all the time, so we might provide outdated data till it gets refreshed, but this is better than providing no printer list at all. If there are a lot of printers, the idle_seconds for the rpc-spoolssd should be increased so that the background task can finish.
