佳能 MX870 打印机仅在状态 LCD 上显示“正在处理”

Question

我的佳能 MX870 在 11.10 中安装得很好，但自从升级到 12.04 后，它就不再工作了。打印机在打印设置中被识别，当我尝试打印测试页时，打印机 LCD 显示“正在处理”消息，但随后消失并且没有任何反应。这是我的日志（请注意，尽管访问日志显示成功，但打印并未成功）：

# /var/log/cups/access_log

找到了解决方案：我最初让打印机在 11.10 下使用 michael gruz ppa 工作，但这在 12.04 中不再有效，并且尝试从 Ubuntu 的打印管理器安装也不起作用。

我发现了一个已更新为 12.04 的 michael gruz ppa：https ://code.launchpad.net/~michael-gruz/+archive/canon-trunk/+packages

我首先使用 Synaptic Package Manager 删除了旧驱动程序，然后添加了新驱动程序：

sudo add-apt-repository ppa:michael-gruz/canon-trunk
sudo apt-get update
sudo apt-get install cnijfilter-mx870series

执行此操作后，使用打印管理器安装打印机即可。
