Ubuntu 20.04 PC 无法在佳能打印机 imageClass LBP7100Cn 上打印?

在从 Ubuntu 20.04 LTS PC 安装打印机驱动程序“linux-UFRII-drv-v500-uken-18.tar.gz”后,我们在给 canon imageClass LBP7100Cn 打印时遇到问题。虽然 Linux 的打印机驱动程序安装成功,但打印机仍未启动。

在分析此问题的过程中,我们发现 Ubuntu 20.04 中有一些日志。(这些日志是在给出打印时间生成的):

E [02/Feb/2021:08:37:05 +0530] [作业 67] src = libcanon_pdlwrapper.c,line = 633,err = -1¥nERROR:src = libcanon_pdlwrapper.c,line = 345,err = 0¥nfree():无效指针 W [02/Feb/2021:09:04:53 +0530] CreateProfile 失败:org.freedesktop.ColorManager.AlreadyExists:profile id 'LBP7100C-7110C-Gray..' 已存在 W [02/Feb/2021:09:04:53 +0530] CreateProfile 失败:org.freedesktop.ColorManager.AlreadyExists:profile id 'LBP7100C-7110C-RGB..' 已存在 W [02/Feb/2021:09:04:54 +0530] CreateProfile 失败:org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-LBP7100C-7110C-Gray..' 已存在 W [02/Feb/2021:09:04:54 +0530] CreateProfile 失败:org.freedesktop.ColorManager.AlreadyExists:profile id 'Canon-LBP7100C-7110C-RGB..' 已存在 E [02/Feb/2021:09:05:34 +0530] [作业 68] src = libcanon_pdlwrapper.c,line = 633,err = -1¥nERROR:src = libcanon_pdlwrapper.c, line = 345, err = 0¥nfree(): 无效指针 E [02/Feb/2021:09:08:25 +0530] [Job 69] src = libcanon_pdlwrapper.c, line = 633, err = -1¥nERROR: src = libcanon_pdlwrapper.c, line = 345, err = 0¥nfree(): 无效指针 E [02/Feb/2021:13:21:14 +0530] [Job 71] src = libcanon_pdlwrapper.c, line = 633, err = -1¥nERROR: src = libcanon_pdlwrapper.c, line = 345, err = 0¥nfree(): 无效指针

Linux Canon LBP7100Cn 驱动程序

转到此页面,https://in.canon/en/support/0100595001

下载 Tarball linux-UFRIILT-drv-v500-uken-18.tar.gz

在档案查看器中打开,转到驱动程序 64 位/Debian/并提取驱动程序文件。

cnrdrvcups-ufr2lt-uk_5.00-1_amd64.deb

使用软件应用程序安装此驱动程序文件,我有 Ubuntu Studio 20 64 位

添加新打印机(删除旧驱动程序),在我的情况下是搜索网络打印机,选择并继续。很简单,尽管确实需要一些调查。

祝你好运 !
