 ### 2. Imprimir HTML (Etiquetas/Layouts)
 
-Converte um código HTML (com suporte a Tailwind CSS) para PDF e imprime na impressora selecionada. Ideal para etiquetas.

+- **Rota:** `/printer/print-html` ou `/printer/:printerName/print-html`
 - **Corpo da Requisição (JSON):**
 
 ```json
 {
   "html": "<div class='text-xl font-bold'>Minha Etiqueta</div>...",
-  "printerName": "POS-80", // Nome exato da impressora (conforme retornado na listagem)
+  "printerName": "POS-80", // Opcional se passado na URL
   "width": "60mm", // Opcional. Largura do papel/etiqueta. Default: 80mm
-  "height": "40mm" // Opcional. Altura da etiqueta. Default: auto
+  "height": "40mm", // Opcional. Altura da etiqueta. Default: auto
+  "jobId": "meu-id-unico-123" // Opcional. ID para idempotência na fila.
 }
 ```
 
 - **Detalhes:**
   - O backend injeta automaticamente o script do Tailwind CSS.
   - O HTML é renderizado via Puppeteer (Chrome headless).
+  - Tarefas são processadas de forma assíncrona via Redis/BullMQ.
