Mac OS X supports discovery of LPR print services via directory services. Any Mac OS X Server that is acting as an Open Directory master can be configured to maintain a list of shared printers. You can configure any printer information you wish in Open Directory, regardless of print server settings. In other words, Open Directory doesn't care where the shared or network printers reside. You use Open Directory to maintain a list of printers that your client computers can easily discover through directory services. Obviously, in order for client computers to discover printers via directory services, they must be configured to access your directory server. See Chapter 3 for more information about directory services.

The printer is now advertised, displaying the attributes with their native names and their Open Directory names (Figure 7.26).
