ubuntu - CUPS 无法打印并且调试消息为空白。建议？

Question

我正在尝试使用戴尔 ppd 打印到戴尔 2350dn。它曾经有效，现在无效，但我很少使用这台打印机，也不知道在此期间发生了什么。

cups 错误日志有:

E [07/Feb/2014:16:11:53 -0800] [Job 140] Job stopped due to filter errors; please consult the error_log file for details.
D [07/Feb/2014:16:11:53 -0800] [Job 140] The following messages were recorded from 16:11:53 to 16:11:53
D [07/Feb/2014:16:11:53 -0800]
---- (above line repeated apx 40 times) ----
D [07/Feb/2014:16:11:53 -0800] [Job 140] End of messages
D [07/Feb/2014:16:11:53 -0800] [Job 140] printer-state=3(idle)
D [07/Feb/2014:16:11:53 -0800] [Job 140] printer-state-message="Filter failed"
D [07/Feb/2014:16:11:53 -0800] [Job 140] printer-state-reasons=none

请注意，调试消息是空白的。没有指示哪个过滤器失败或原因(除了 error_log 和打印中的“过滤器失败”)。

我已尝试多次重新安装打印机，但没有任何变化。

在此期间采取的一项措施是安装一组我安装的软件包以支持佳能 MF4890dw(cndrvcups-ufr2-us 和 cndrvcups-common)。我删除(清除)了这两个，但情况没有改变。

有什么建议么？

我的情况是由于缺少库，如 cups error 所示。日志片段:

D [07/Apr/2014:18:42:50 -0300] [Job 6] 
/usr/lib/cups/filter/watermarkfilter: error while loading shared libraries: 
libcupsimage.so.2: cannot open shared object file: No such file or directory 
D [07/Apr/2014:18:42:50 -0300] [Job 6] 
/usr/lib/cups/filter/rastertoprinterbin: error while loading shared libraries: 
libcupsimage.so.2: cannot open shared object file: No such file or directory

请注意您的打印机 驱动程序是 32 位或 64 位 ，所以你应该安装正确的库拱。
