对这个有什么想法吗？我正在尝试从运行 OSX 10.11 El Capitan 的 Mac 打印到在 Debian 上运行的 CUPS 打印机。当我尝试打印时，我的 /var/log/cups/error_log 内容如下：
D [12/Oct/2015:00:59:04 +0100] [Client 3] Accepted from [v1.fe80::a65e:60ff:fec1:9b01+eth0]:55661 (IPv6)

然后用数百万行（字面意思）填充日志文件，直到整个分区已满！
Mac机器说：“等待身份验证”，但我不知道在CUPS配置中请求了身份验证，所以我真的很茫然。如果有帮助的话，我可以发布我的杯子配置。
任何指导将不胜感激！
谢谢，朱利安
答案1
我也有这个问题。就我而言，事实证明需要更改服务器端配置，具体来说，在“管理”->“服务器”中，启用“允许从互联网打印”。
不太确定原因，但似乎 El Capitan 可能更喜欢 IPv6，而服务器端的 CUPS 将此解释为“互联网”访问而不是本地网络。
哈！
