+# Cups
+### 📌 Sobre o Projeto
+Uma compilação simples do cups com algumas alterações que para o meu contexto eram importantes, tais como:
+1. Versão mais atualizada
+2. Filtro para leitura de arquivos docx/xlsx
+3. Suporte a Nomes para instalar impressoras ex: imp.escritorio
+4. Pacote de drivers mais completo
+---
+
+### 🚀 Como Usar
+
+#### Via docker compose (Meu preferido.)
+
+```yaml
+---
+services:
+  cups:
+    image: grandow/cups:2.4.12-office
+    container_name: cups
+    restart: unless-stopped
+    ulimits:
+        nofile:
+          soft: "65536"
+          hard: "65536"
+    ports:
+        - "631:631"
+        - "5353:5353/udp"
+    environment:
+        - USERNAME=admin
+        - PASSWORD=cups
+        - TZ="America/Sao_Paulo"
+    volumes:
+        - "./cups/:/etc/cups/"
+```
