[Samba] printcap cache time using registry config on Ubuntu 9.04 samba 3.3.2

[Glenn T. Arnold]

I have been reading the man page on printcap cache time setting and have some questions. How much load does this put on a server if you have the setting less then 60? The reason I have this setting less than 60 is when I use an all registry samba configuration the printers do not show up if you browse the server or when you goto the Windows XP pc with the printer already connect shows printer status opening, but if you wait the default time period that samba sets for the printcap cache time the printer will eventually show up under the server. When I used the smb.conf file I did not observer this behavior. The reason I am using the all registry conf is to save some memory on the server. I have observed this behavior on another customers server with the same version ubuntu. The printcap cache time setting less than 60 seems to fix the issue or mask the issue enough to be liveable, but I want to make sure that I am not missing anything in configuring samba. Here is my config.
