+
+### API设计
+#### 飞鹅打印模块API
+1. `GET /api/feie/printers` - 查询打印机列表
+2. `POST /api/feie/printers` - 添加打印机
+3. `DELETE /api/feie/printers/{printerSn}` - 删除打印机
+4. `POST /api/feie/print` - 提交打印任务（支持延迟打印）
+5. `GET /api/feie/tasks/{taskId}` - 查询打印任务状态
+6. `GET /api/feie/tasks` - 查询打印任务列表
+7. `POST /api/feie/tasks/{taskId}/cancel` - 取消打印任务
+8. `POST /api/feie/tasks/{taskId}/retry` - 重试打印任务
+9. `GET /api/feie/config` - 查询打印配置
+10. `PUT /api/feie/config` - 更新打印配置
+
+#### 飞鹅API接口（需要封装）
+1. **打印机管理**
+   - `Open_printerAddlist` - 添加打印机
+   - `Open_printerDelList` - 删除打印机
+   - `Open_queryPrinterStatus` - 查询打印机状态
+
+2. **打印任务管理**
+   - `Open_printMsg` - 打印小票
+   - `Open_queryOrderState` - 查询订单打印状态
+   - `Open_queryOrderInfoByDate` - 根据时间查询订单
+
+## 集成点
+### 与现有系统集成
+1. **订单模块集成**：
+   - 订单支付成功时触发打印事件（延迟2分钟执行）
+   - 订单发货时触发打印事件（立即执行）
+   - 订单退款时触发打印取消事件
+   - 订单详情页添加打印按钮
+   - 订单列表添加批量打印功能
+   - 打印状态同步到订单备注
+
+2. **配置模块集成**：
+   - 使用现有的配置管理机制
+   - 支持租户级打印配置
+   - 配置项包括：默认打印机、打印触发条件、防退款延迟时间、重试策略等
+
+3. **事件系统集成**：
+   - 监听订单支付成功事件（触发延迟打印）
+   - 监听订单发货事件（触发立即打印）
+   - 监听订单退款事件（触发打印取消）
+
+### 数据流
+#### 防退款延迟打印流程（支付成功后）
+1. 订单支付成功 → 触发打印事件 → 打印模块接收事件
+2. 打印模块查询租户打印配置 → 获取防退款延迟时间（默认120秒/2分钟）
+3. 生成打印内容（小票模板） → 创建延迟打印任务
+4. 记录打印任务到数据库，状态为`DELAYED`，设置`scheduled_at`为当前时间+延迟时间
+5. 启动延迟任务调度器，等待延迟时间到达
+6. **延迟期间监控退款事件**：
+   - 如果2分钟内发生退款 → 取消打印任务（状态改为`CANCELLED`，原因`REFUND`）
+   - 如果2分钟内无退款 → 继续执行打印
+7. 延迟时间到达后，检查订单状态：
+   - 如果订单已退款 → 取消打印任务
+   - 如果订单正常 → 调用飞鹅API提交打印任务
+8. 提交打印任务 → 状态改为`PRINTING` → 记录飞鹅任务ID
+9. 定时轮询打印状态 → 更新任务状态
+10. 打印成功 → 状态改为`SUCCESS` → 更新订单备注
+11. 打印失败 → 根据重试策略重试
+
+#### 直接打印流程（发货时）
+1. 订单发货 → 触发打印事件 → 打印模块接收事件
+2. 打印模块查询租户打印配置 → 获取默认打印机
+3. 生成打印内容（发货单模板） → 调用飞鹅API提交打印任务
+4. 记录打印任务到数据库 → 返回任务ID
+5. 定时轮询打印状态 → 更新任务状态
+6. 打印成功 → 更新订单备注
+7. 打印失败 → 根据重试策略重试
+
+#### 手动打印流程
+1. 用户在订单详情页点击打印按钮 → 调用打印API
+2. 选择打印机（或使用默认打印机） → 生成打印内容
+3. 提交打印任务 → 显示打印状态
+4. 用户可在打印任务列表查看打印状态
+
+## 打印取消逻辑
+### 取消场景定义
+1. **退款取消（REFUND）**
+   - **触发条件**：订单在延迟打印期间发生退款
+   - **取消时机**：退款事件发生时立即取消
+   - **业务意义**：避免无效打印，节省打印资源
+   - **实现方式**：监听退款事件，自动调用取消接口
+
+2. **手动取消（MANUAL）**
+   - **触发条件**：管理员手动取消打印任务
+   - **取消时机**：任何时间点
+   - **业务意义**：人工干预打印流程
+   - **实现方式**：提供手动取消按钮
+
+3. **超时取消（TIMEOUT）**
+   - **触发条件**：打印任务长时间未完成
+   - **取消时机**：超过配置的超时时间
+   - **业务意义**：避免僵尸任务占用资源
+   - **实现方式**：定时任务检查超时任务
+
+### 取消规则
+1. **状态检查**：只有特定状态的任务才能取消（`PENDING`, `DELAYED`, `PRINTING`）
+2. **幂等性保证**：同一任务只能取消一次，防止重复取消
+3. **日志记录**：每次取消都记录详细的原因和时间
+4. **通知机制**：任务取消时通知相关人员
+
+## 配置管理
+### 租户级配置项
+1. `feie.enabled` - 是否启用飞鹅打印
+2. `feie.default_printer_sn` - 默认打印机序列号
+3. `feie.auto_print_on_payment` - 支付成功时自动打印
+4. `feie.auto_print_on_shipping` - 发货时自动打印
+5. `feie.anti_refund_delay` - 防退款延迟时间（秒，默认120秒/2分钟）
+6. `feie.retry_max_count` - 最大重试次数
+7. `feie.retry_interval` - 重试间隔（秒）
+8. `feie.task_timeout` - 任务超时时间（秒）
+9. `feie.receipt_template` - 小票模板
+10. `feie.shipping_template` - 发货单模板
+
+## 兼容性要求
+1. **API兼容性**：新增API端点，不影响现有API
+2. **数据库兼容性**：新增表，不影响现有表结构
+3. **UI兼容性**：新增页面和组件，遵循现有UI规范
+4. **订单流程兼容性**：打印功能作为可选扩展，不影响核心订单流程
+
+## 风险与缓解
+### 风险1：飞鹅API调用失败影响订单流程
+- **缓解措施**：打印功能异步处理，不影响订单核心流程
+- **降级策略**：打印失败时记录日志，不影响订单状态

+
+### 风险4：延迟打印调度器故障
+- **缓解措施**：实现调度器健康检查
+- **故障恢复**：支持调度器重启后恢复未完成任务
+- **监控告警**：监控调度器运行状态
+
+### 风险5：网络延迟影响打印响应
+- **缓解措施**：异步处理打印任务，不阻塞用户操作
+- **超时设置**：设置合理的API调用超时时间
+- **状态轮询**：通过轮询方式获取打印状态

+
+### API设计 [Source: docs/prd/epic-005-feie-printer-integration.md#API设计]
+#### 飞鹅打印模块API
+1. `GET /api/feie/printers` - 查询打印机列表
+2. `POST /api/feie/printers` - 添加打印机
+3. `DELETE /api/feie/printers/{printerSn}` - 删除打印机
+4. `POST /api/feie/print` - 提交打印任务（支持延迟打印）
+5. `GET /api/feie/tasks/{taskId}` - 查询打印任务状态
+6. `GET /api/feie/tasks` - 查询打印任务列表
+7. `POST /api/feie/tasks/{taskId}/cancel` - 取消打印任务
+8. `POST /api/feie/tasks/{taskId}/retry` - 重试打印任务
+9. `GET /api/feie/config` - 查询打印配置
+10. `PUT /api/feie/config` - 更新打印配置
+
+#### 飞鹅API接口（需要封装）
+1. **打印机管理**
+   - `Open_printerAddlist` - 添加打印机
+   - `Open_printerDelList` - 删除打印机
+   - `Open_queryPrinterStatus` - 查询打印机状态
+
+2. **打印任务管理**
+   - `Open_printMsg` - 打印小票
+   - `Open_queryOrderState` - 查询订单打印状态
+   - `Open_queryOrderInfoByDate` - 根据时间查询订单
+
+### 编码标准 [Source: architecture/coding-standards.md]
+- **代码风格**: TypeScript严格模式，一致的缩进和命名
+- **测试框架**: 使用Vitest + Testing Library + hono/testing
+- **测试位置**: `__tests__` 文件夹与源码并列
+- **覆盖率目标**: 核心业务逻辑 > 80%
+- **测试类型**: 单元测试、集成测试、E2E测试
+- **RPC客户端架构**: 使用单例模式的客户端管理器，类型安全的Hono RPC
+
+### 测试标准
+- **测试文件位置**: 每个包独立的 `tests/` 目录
+- **测试框架**: Vitest 2.x
+- **测试模式**: 单元测试覆盖核心逻辑，集成测试验证API功能
+- **覆盖率要求**: 核心业务逻辑 > 80%
+- **测试数据**: 使用测试数据库，避免污染生产数据
+- **错误处理测试**: 测试各种错误场景和边界条件
+
+### 多租户实现要求
+- **包命名**: 使用 `-mt` 后缀表示多租户包
+- **租户ID字段**: 所有实体必须包含 `tenant_id` 字段
+- **数据隔离**: 通过租户ID实现数据查询隔离
+- **路由中间件**: 实现多租户路由中间件，自动注入租户上下文
+- **权限控制**: 确保租户只能访问自己的数据
+
+### 防退款延迟打印机制
+- **默认延迟时间**: 120秒（2分钟）
+- **状态管理**: 打印任务状态包括 `PENDING`、`DELAYED`、`PRINTING`、`SUCCESS`、`FAILED`、`CANCELLED`
+- **取消场景**: `REFUND`（退款）、`MANUAL`（手动取消）、`TIMEOUT`（超时）
+- **调度器设计**: 使用 `node-cron` 实现定时任务调度
+- **退款监听**: 监听订单退款事件，自动取消延迟打印任务
+
+### 项目结构对齐说明
+- 新包 `@d8d/feie-printer-module-mt` 应放置在 `packages/` 目录下
+- 包结构应遵循现有的多租户模块包模式
+- 需要与现有的 `@d8d/orders-module-mt` 集成，监听订单支付成功事件
+- API路由应遵循现有的RESTful API设计模式
