我正在尝试将 Canon imageRUNNER ADVANCE C5535 设置为通过 IPP 使用 CUPS 进行打印。
- 我已在打印机管理中启用 IPP
- 我已使用制造商的驱动程序 (Canon iR-ADV C5535/5540 UFR II) 和 url 将打印机添加到 CUPS”http://10.11.75.21/ipp“（10.11.75.21是打印机的IP）
- 我正在通过 CUPS 的 Web 界面打印测试页。
- 作业标记为已完成，但未打印任何页面。
在深入研究日志后，打印机似乎正在取消作业。我不知道为什么。日志在这里：

我认为身份验证可能存在问题，因此我尝试将打印机的网址更改为http://名称:[电子邮件受保护]/ip（这是验证的正确方法吗？），但唯一的结果是作业在处理过程中陷入困境。
