我有一台佳能 Pixma TS305，我用它来打印 110x290cm 的自定义尺寸标签。
通过无驱动程序的 dnssd，可以轻松在本地网络中设置打印机，并且安装脚本运行良好。打印工作正常，我能够在 /etc/cups/ppd/.. 目录中的给定 PPD 文件中添加自定义纸张尺寸。
现在我正尝试通过 VPN 访问该打印机。在 Ubuntu 中，我通过查找主机并选择 IPP 或 JetDirect 协议安装了一台新打印机。安装程序选择了正确的驱动程序，我可以打印测试页。
当我尝试打印到自定义尺寸时，问题就出现了。我尝试在 PPD 中指定尺寸，甚至通过 Ubuntu 打印系统对话框进行打印。打印结束时，打印机队列中的状态为“已停止”。http://localhost:631/ 上的 cups 界面显示“过滤失败”，/var/log/cups/error_log 给出了记录消息的摘要：

当我尝试打印到已知的预定义纸张尺寸（A4、明信片等）时，打印工作正常。一旦我更改纸张尺寸，就会出现此错误。
打印机确实能够打印自定义尺寸。但由于某种原因，IPP/JetDirect 方式试图拦截并设置错误的文档尺寸，并且无法应用过滤器。
有机会得到这个工作吗？谢谢。

好的，我找到了解决方案：
我将之前安装并运行的 dnssd 打印机的打印功能与受此线程启发的新设置的远程 IPP 打印机进行了比较：

新设置的打印机明显缺少选项自定义.WIDTHxHEIGHT因此非标准页面尺寸的打印命令也会失败。
在安装同一台设备时，我对这种差异感到困惑。然后，我在一次又一次尝试修改打印机时注意到 http://localhost:631/ cups 客户端中的打印机驱动程序名称存在差异。之前工作的打印机驱动程序名称后面跟着

https://istopwg.github.io/ipp/evefaq.html
我假设佳能提供的原始 install.sh 脚本会以某种方式利用 IPP Everywhere 功能，但它无法检测到不同子网中的远程打印机。因此，我搜索了强制 cups 检测和远程添加打印机的方法，并找到了此 Oracle 文档
https://docs.oracle.com/cd/E36784_01/html/E36821/gmfou.html
使用有用的命令，例如
lpinfo --make-and-model Canon -m
它提供了一系列支持的佳能打印机以及 TS300 系列 PPD
canonts300.ppd Canon TS300 series Ver.5.50
lsb/usr/canonts300.ppd Canon TS300 series Ver.5.50
但有趣的是，这个司机也
everywhere IPP Everywhere
将所有内容放在一起并使用 Oracle 文档提供的命令添加新打印机如下：
lpadmin -p TS305 -E -v ipp://192.168.57.105:631 -m everywhere
我再次使用 PPD 中设置的自定义尺寸进行打印。更重要的是，与原始佳能驱动程序相比，现在我看到了扩展的打印机功能。希望这对某些人有所帮助。
