CUPS打印收据时如何固定打印方向？

搭建简易POS系统，使用Seiko Instruments RP-D10收据打印机，系统生成的PDF文件正确，但CUPS打印时存在以下问题：

• 始终以纵向模式打印，当收据高度小于宽度时，CUPS自动将内容横向发送至打印机，导致打印效果异常
• 收据左侧约60mm内容被裁切
• 手动设置打印方向及默认选项无效，无法通过固定文档尺寸解决可变长度收据的问题

1. 修改PPD文件，强制默认纵向并修正旋转逻辑 #

编辑RP-D10.ppd文件，添加方向控制配置并调整旋转参数：

• 添加方向选择项，强制默认纵向：

*OpenUI *Orientation/Orientation: PickOne
*OrderDependency: 15 AnySetup *Orientation
*DefaultOrientation: Portrait
*Orientation Portrait/Portrait: "<<</Orientation 0>>setpagedevice"
*Orientation Landscape/Landscape: "<<</Orientation 1>>setpagedevice"
*CloseUI: *Orientation

• 将*LandscapeOrientation: Plus90修改为*LandscapeOrientation: Minus90，避免旋转后内容偏移导致裁切

修改后重启CUPS服务：

sudo systemctl restart cups

2. 强制打印机使用固定宽幅长页面 #

通过命令行设置打印机默认选项，指定使用72mm宽、1000mm长的页面（适配可变长度收据），并锁定纵向：

lpadmin -p RP-D10 -o PageSize=X72MMY1000MM -o Orientation=Portrait

也可以先停止CUPS服务，直接编辑printers.conf，在<Printer RP-D10>块内添加：

Option PageSize X72MMY1000MM
Option Orientation Portrait

3. 替换CUPS过滤器（可选） #

当前使用的rastertosii过滤器可能存在方向处理缺陷，可尝试替换为通用ESC/POS过滤器：

1. 安装rastertoescpos（Debian/Ubuntu系统示例）：

sudo apt install printer-driver-escpos

2. 修改PPD文件中的过滤器配置：

*cupsFilter:            "application/vnd.cups-raster 0 rastertoescpos"

3. 重启CUPS服务后测试打印

4. 打印PDF时强制指定参数 #

打印生成的PDF时，明确指定页面尺寸和方向，避免CUPS自动判断：

lp -d RP-D10 -o PageSize=X72MMY1000MM -o Orientation=Portrait receipt.pdf

如果是应用程序内调用打印，确保传递这些参数给CUPS打印命令。
