打印机是 Brother MFC-J430W，操作系统是 Ubuntu 21.04。连接是通过 USB 电缆进行的。一开始，我将打印机插入计算机，它显然识别了它并安装了驱动程序，但是当我尝试打印时，什么也没有发生。虽然它显示“打印完成”。
然后我去了兄弟支持网站并下载了此型号的驱动程序。他们没有专门用于 ubuntu 系统的驱动程序，所以我下载了适用于 linux debian 的驱动程序。
在通过 CLI 安装驱动程序包的过程中，输出如下：
dpkg -i --force-all mfcj430wlpr-3.0.1-1a.i386.deb

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
brscan-skey:i386 : Depends: libc6:i386 (>= 2.3.4-1) but it is not installable
Depends: libsane:i386 (>= 1.0.11-3) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
查看上面的警告信息，很多都警告驱动程序与系统架构不匹配。但是没有其他可用的驱动程序，或者至少我不知道。
当我在安装此驱动程序后尝试打印时，正如预期的那样，什么都没有发生，现在没有任何“打印完成”的消息。
有人有解决方案吗？有可能解决这种架构不兼容问题吗？任何回复都将不胜感激。非常感谢

你去
https://github.com/alexpevzner/sane-airscan（主页）
然后
https://download.opensuse.org/repositories/home:/pzz/xUbuntu_20.04/amd64/
您安装ipp-usb
您汇报是否成功。
（事先清除 ippusbxd）。
我应该好好读一读！以上说明适用于 Ubuntu 20.04 上的 amd64。Daniel 要做的就是检查 ipp-usb 是否已从 arm64 存档中安装（应该已安装）：apt install ipp-usb
插入打印机。检查 ipp-usb 服务是否处于活动状态systemctl status ipp-usb.service。无人驱动打印应该可以立即使用。（如果不是，我还有另一种方法来实现）。
概括
不幸的是，MFC-J430W 太旧了，无法在任何架构上利用 ipp-usb。Brother 也不提供 arm64 驱动程序。据我所知，让它工作的唯一机会是使用无线和阅读这。
MFC-J430W 可能需要固件更新才能获得 AirPrint 服务。2013 年有一款这里。IPP-over-USB 协议于 2012 年获得批准，所以谁知道呢，ipp-usb 也可能有效。该用户的帖子很有用。
