我最近购买了一台 Canon I-SENSYS LBP7010C 打印机,但在让它在我的 Linux Mint 17 系统上运行时遇到问题。我成功地从佳能网站安装了驱动程序,但是当我尝试打印某些内容时,它卡在“将数据发送到打印机”上。

司机

是我从佳能网站安装的驱动程序。它被称为适用于 Linux 版本 2.70 的 CAPT 打印机驱动程序(64 位)。

遵循 Ubuntu 的调试打印问题

打印机已连接并打开电源。

打开终端/控制台并检查 USB 内核模块是否已加载

$ lsmod | grep usb
usblp                  22891  0 
usbhid                 52659  0 
hid                   106148  2 hid_generic,usbhid

从计算机上拔下 USB 打印机电缆并输入以下命令:

$ tail -f /var/log/syslog 

重新连接 USB 打印机电缆,您应该会看到出现一些消息。

正如您在输出中看到的,我为此打印机添加了两个不同的 CUPS 条目。添加一项是因为 CUPS 自动检测到打印机,另一项是通过中列出的步骤添加的佳能CaptDrv190

检查 USB 子系统是否正确检测到打印机,并确定其 USB 供应商/产品 ID 以及 USB 总线和设备地址:

$ lsusb
Bus 001 Device 006: ID 04a9:271c Canon, Inc. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 0603:00f2 Novatek Microelectronics Corp. Keyboard (Labtec Ultra Flat Keyboard)
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

检查打印机的设备文件是否已正确创建以及所有权(“root lp”)和权限(非 HP:“crw-rw-r--”,HP:“crw-rw-r--+”)放:

$ ls -l /dev/usb/lp* /dev/bus/usb/*/*
crw-rw-r-- 1 root root 189,   0 mar 30 14:46 /dev/bus/usb/001/001
crw-rw-r-- 1 root lp   189,   5 mar 30 14:57 /dev/bus/usb/001/006
crw-rw-r-- 1 root root 189, 128 mar 30 14:46 /dev/bus/usb/002/001
crw-rw-r-- 1 root root 189, 129 mar 30 14:46 /dev/bus/usb/002/002
crw-rw-r-- 1 root root 189, 256 mar 30 14:46 /dev/bus/usb/003/001
crw-rw-r-- 1 root root 189, 257 mar 30 14:46 /dev/bus/usb/003/002
crw-rw-r-- 1 root root 189, 384 mar 30 14:46 /dev/bus/usb/004/001
crw-rw-r-- 1 root root 189, 512 mar 30 14:46 /dev/bus/usb/005/001
crw-rw---- 1 root lp   180,   1 mar 30 14:57 /dev/usb/lp1

这里似乎有一个我以前没有看到的问题。/dev/usb/lp1实际上缺少其他人的读取权限。

确定打印机的设备 ID 字符串:

$ sudo usb_printerid /dev/usb/lp1
GET_DEVICE_ID string:
MFG:Canon;MDL:LBP7010C/7018C;CMD:CAPT;VER:3.0;CLS:PRINTER;DES:Canon LBP7010C/7018C

查看 CUPS 是否检测到您的打印机:

$ lpinfo -v
network ipp14
direct usb://Canon/LBP7010C/7018C?serial=0000A2F0Q78n
direct ccp
network lpd
network http
network ipp
network https
network socket
serial serial:/dev/ttyS0?baud=115200
network ipps

系统日志

接下来是我的系统日志,记录插入并打开打印机、通过系统配置打印机添加打印机,然后在出现提示时尝试打印测试页的过程。

中没有消息/var/log/cups/error_log

我尝试过的事情

  • 为我的 MacBook 安装驱动程序并让它正常工作。
  • 重新启动打印机、计算机和cups 服务。
  • 正在安装printer-driver-cjet
  • 将我自己添加到lp组中lpadmin
  • 遵循 Ubuntu 指南佳能CaptDrv190。最值得注意的是,我再次添加了打印机lpadmin(见下文)并安装了损坏的依赖项captfilter。这样做,我发现了一个新条目/dev/usb/lp1(如上所示)。

更新:打印机通过lpadmin

使用我添加的新打印机,作业完成,但没有真正打印任何内容。运行时captstatusui -P LBP7010C显示 UI 提示“通信错误”。

更新:/dev条目

进行一些更改后,我发现了一个新条目:/dev/usb/lp1。我尝试将其设置/dev/lp0为 devpath ccpd.conf

# Canon Printer Daemon for CUPS Configuration Data

<Path>
# CUPS configuration file path.
#  Default  /etc/cups/

CUPS_ConfigPath   /etc/cups/

# Log directory path.
#  LogDirectoryPath /var/log/CCPD/

</Path>

</Printer>

<Ports>
# Status monitoring socket port.
#  Default 59787

</Ports>

更新:打印!

我不知道我到底做了什么,但现在有时可以打印页面。至少在重新启动打印机后它可以工作,尽管打印的页面非常淡。我不知道这是什么原因,但以下佳能常见问题解答表明墨粉盒已用完。我不明白一台全新的打印机怎么会出现这种情况,但该列表上的其他内容似乎都不可信。
