The /etc/cups/client.conf and ~/.cups/client.conf files contain up to two directives that determine how the client behaves. Each directive is listed on a line by itself followed by its value. Comments are introduced using the number sign ("#") character at the beginning of a line.

## Encryption

### Examples

    Encryption Never
    Encryption IfRequested
    Encryption Required
    Encryption Always

### Description

The `Encryption` directive specifies the default encryption settings for the client.

The default setting is IfRequested.

## ServerName

### Examples

    ServerName foo.bar.com
    ServerName 11.22.33.44
    ServerName foo.bar.com:8631

### Description

The `ServerName` directive specifies sets the remote server that is to be used for all client operations. That is, it redirects all client requests to the remote server.

The default port number is 631 but can be overridden by adding a colon followed by the desired port number to the value.

The default is to use the local server ("localhost") or domain socket, if so configured.
