Quick Install

Server (Docker)

docker run -d \
  --name printmaster-server \
  -p 9090:9090 \
  -v printmaster-data:/var/lib/printmaster/server \
  -e ADMIN_PASSWORD=your-secure-password \
  ghcr.io/printmaster-org/printmaster-server:latest

Access at http://localhost:9090 with username admin and your chosen password.

Agent (Windows)

Download and run the MSI installer from GitHub Releases.

Agent (Linux)

# Debian/Ubuntu
curl -fsSL https://packages.printmaster.work/install.sh | sudo bash

Server Installation

The server provides centralized management for multiple agents. If you only need to monitor printers at a single site, you can run the agent standalone without a server.

Docker is the recommended deployment method for the server.

Prerequisites

  • Docker Engine 20.10 or later
  • Docker Compose (optional but recommended)

Using Docker Run

# Basic setup
docker run -d \
  --name printmaster-server \
  -p 9090:9090 \
  -v printmaster-data:/var/lib/printmaster/server \
  -v printmaster-logs:/var/log/printmaster/server \
  -e ADMIN_PASSWORD=your-secure-password \
  ghcr.io/printmaster-org/printmaster-server:latest

Using Docker Compose

Create a docker-compose.yml file:

version: '3.8'
services:
  printmaster-server:
    image: ghcr.io/printmaster-org/printmaster-server:latest
    container_name: printmaster-server
    ports:
      - "9090:9090"
    volumes:
      - printmaster-data:/var/lib/printmaster/server
      - printmaster-logs:/var/log/printmaster/server
    environment:
      - ADMIN_PASSWORD=your-secure-password
      - LOG_LEVEL=info
      - BEHIND_PROXY=false
    restart: unless-stopped

volumes:
  printmaster-data:
  printmaster-logs:

Start with:

docker compose up -d

Environment Variables

VariableDefaultDescription
ADMIN_PASSWORDprintmasterAdmin password (set before first run!)
LOG_LEVELinfoLogging level: debug, info, warn, error
BEHIND_PROXYfalseSet to true if behind a reverse proxy
BIND_ADDRESS0.0.0.0Address to bind to
HTTP_PORT9090HTTP port
HTTPS_PORT9443HTTPS port (when TLS enabled)

Important: Set ADMIN_PASSWORD before the first run. The password can only be set during initial database creation.

Behind a Reverse Proxy

If using Nginx Proxy Manager, Traefik, or another reverse proxy:

environment:
  - BEHIND_PROXY=true
  - BIND_ADDRESS=0.0.0.0

Configure your proxy to:

  • Forward to port 9090
  • Enable WebSocket support (required for real-time features)
  • Handle SSL termination

Unraid

  1. Using Community Applications (Easiest):

    • Install the Community Applications plugin
    • Search for “PrintMaster Server”
    • Click Install and configure

  2. Manual Docker Setup:

    • Go to Docker tab → Add Container
    • Repository: ghcr.io/printmaster-org/printmaster-server:latest
    • Port: 9090 → 9090
    • Path: /mnt/user/appdata/printmaster-server/data → /var/lib/printmaster/server
    • Path: /mnt/user/appdata/printmaster-server/logs → /var/log/printmaster/server

See Unraid Deployment Guide for detailed instructions.

Manual Server Installation

Download the server binary from GitHub Releases and run:

# Linux/macOS
./printmaster-server

# Windows
.\printmaster-server.exe

Agent Installation

Windows

  1. Download the latest MSI from GitHub Releases
  2. Run the installer
  3. The agent will be installed as a Windows service and start automatically
  4. Access the web UI at http://localhost:8080

Manual Installation

# Download the binary
Invoke-WebRequest -Uri "https://github.com/printmaster-org/printmaster/releases/latest/download/printmaster-agent-windows-amd64.exe" -OutFile "printmaster-agent.exe"

# Install as service (requires Administrator)
.\printmaster-agent.exe --service install

  sudo gpg --dearmor --yes -o /etc/apt/keyrings/printmaster.gpg
sudo chmod 0644 /etc/apt/keyrings/printmaster.gpg

# Configure APT to trust this key only for the PrintMaster repository
echo "deb [signed-by=/etc/apt/keyrings/printmaster.gpg] https://packages.printmaster.work stable main" | \
  sudo tee /etc/apt/sources.list.d/printmaster.list

# Install
sudo apt-get update

Docker Agent

The agent can also run in Docker for specialized deployments:

docker run -d \
  --name printmaster-agent \
  --network host \
  -v printmaster-agent-data:/var/lib/printmaster/agent \
  ghcr.io/printmaster-org/printmaster-agent:latest
