操作系统：Ubuntu 13.10 64位
驱动程序：CAPT v2.60 -> debian 软件包 64 位
打印机：LBP3100B
关于这个“答案”，我已经在我的计算机上安装了佳能 CAPT 驱动程序，但是当我尝试启动/重新启动 ccpd 时，出现此错误：
但是，除非我启动 ccpd，否则打印机无法工作。以下是 的内容/etc/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 entries.
# Mapping each "Printer Name" to each "Printer Device Port".
# The "Printer Name" has to be identical to the CUPS printer queue name.
# For example, if you prepare a printer named "LBP3200" as a CUPS printer
# queue name, and the printer is connected to the USB port "/dev/usb/lp0",
# you can use the following three lines example just by removing the
# comment symbol "#" of each line.
#<Printer LBP3200>
#DevicePath /dev/usb/lp0
#</Printer>
<Printer LBP3100B>
DevicePath /dev/usb/lp0
</Printer>
<Ports>
# Status monitoring socket port.
# Default 59787
UI_Port 59787
PDATA_Port 59687
</Ports>
取消注释LogDirectoryPath /var/log/CCPD/并尝试打印页面后，似乎未创建日志文件：
$ ls /var/log/CCPD/
ls: cannot access /var/log/CCPD/: No such file or directory
