The server startup process automatically generates the printers.conf file
if the server attempts to add an entry to the local file and the file does not
exist. Also, the servers compare the content of the object database to the local
file and add objects to it if they are in the database but not in the local file.
Because the object creation operation updates the local file only on the
host where you executed the operation, the information is not available to
clients or servers on other hosts. Therefore, when using the Local File Name
Service in a distributed environment, you should create the configuration
file in advance and copy it to all hosts that run clients or servers.
You can create the printers.conf file with an editor, or you can create the
file by creating all print objects from a single host. However, in the second
case, because you do not create servers with the create operation, you must
manually add the server entries to the file for each different host. You will
have to update the file on all hosts if you delete an object.
For the Local File Name Service:
• The printers.conf file must exist in the /etc directory and it must
have the access rights of rw-r--r--.
• The file owner must be root.
3.2 Network Information Service
Network Information Service (NIS) uses the same format for printer
configuration entries that is used for the Local File Name Service. However,
NIS provides a means for administering and distributing that same printer
configuration data to an entire NIS domain.
The most important difference between using Local File Name Service and
using NIS is that the print system cannot modify NIS entries. Instead, you
must manually update an NIS entry in an NIS file. You must either have
the authority to make changes to the NIS file or have a proxy administrator
with the authority to make the changes.
