请帮助解决一个小打印机问题。
我在 Ubuntu 12.10 上使用 Sharp-MX-2310U 网络打印机。按照所有常规设置并查看杯子，localhost:631/printers/我看到打印机，但没有打印作业，/var/spool/cups只是不断填充未完成的作业。
打印机属性显示墨水状态等，所以我确实连接到打印机，但localhost:631/printers/显示：
SHARP-MX-2310U SHARP MX-2310U 办公室 Sharp MX-2300N Foomatic/pxlcolor (推荐) 空闲 - “等待打印机完成。”
查看后localhost:631/admin/log/error_log我发现了一些错误，但没有明显的错误。

我有同样的问题，只是我的佳能 1023N 是通过以太网连接的。我遇到了同样的错误。这看起来像是杯具的一个已知错误。现在收到了很多报告：
https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1053443
我希望我在安装 12.10 之前就知道这一点，因为据说 12.04 没有这个问题。
