我正在构建一个简单的POS系统，并有一台收据打印机。我已经基本完成了系统，但CUPS打印所有人像。这意味着，如果收据短于宽度，CUPS会将其横向发送到打印机，这看起来完全错误(并从收据的左手边夹住约60毫米(。
我的系统会创建一个PDF，然后将其发送到打印机。PDF生成正确，如何让CUPS停止旋转打印？
我看到了一些答案，比如确保文档完全符合预期的输入，但这对可变长度的收据不起作用。
我还尝试在打印时手动设置方向，并将其作为默认选项，但CUPS似乎忽略了任何旋转指令。
有问题的打印机是Seiko Instruments RP-D10。

我遇到了完全相同的问题。cups似乎通过它的pdftopdf过滤器发送您的作业。这个过滤器然后在它认为必要的时候自动旋转页面。我找到了两种方法来解决这个问题：
- 使用
-o nopdfAutoRotate打印选项，或者 - 用一个简单的shell脚本替换
pdftopdf过滤器(在/usr/lib/cups/filter中(，该脚本只将stdin传递到stdout：
#!/bin/sh
cat -
