YOUR SETUP

A room that grows with you.

Connect local printers, check their capabilities, and keep your fleet in one place.

Your printers

FIND ON YOUR NETWORK

Discover Moonraker printers

Scan a private IPv4 subnet on one port. Results are checked with read-only requests; nothing is added automatically. For multiple instances, scan again with their other ports.

MATERIAL INVENTORY

Spoolman connection

Connect an existing Spoolman server to browse materials and manage reviewed spool records. Testing the connection only reads inventory.

Connect to Spoolman

Server addressUse host.docker.internal for a server on the Docker host, or spoolman for a service on the same Docker network.PortPublished port on the host, or 8000 for a standard Spoolman container.

Browser URL (optional)The address your browser can reach. Set this for an internal Docker service or reverse proxy; it does not change API routing.

Import history stays with its original server and becomes available when you reconnect. Existing Spoolman records are never moved or deleted. Inventory writes keep their separate host policy.

KNOW WHAT CONNECTS

Compatibility

Support depends on the exposed API and firmware, not just the printer brand. Automated coverage is separate from testing on physical hardware.

MADE FOR THE WORKSHOP

Support Printroom

Printroom is free and open source. If it helps keep your room organized, an optional tip supports development and documentation.

Deployment & scale

Up to 64 saved printers, eight concurrent printer polls, and four visible camera connections per dashboard. Two physical K2 Plus printers are qualified here; larger fleets need testing on their own host and network. Offline printers can increase refresh time; source ages remain visible.

Use private IPv4 addresses reachable from the service. DNS names, IPv6, HTTPS printer endpoints and reverse-proxy path prefixes are not supported yet. Subnet discovery does not cross unrouted VLANs or rely on mDNS. Generic cameras require a named stream in go2rtc.

Printer profiles are saved in the persistent data volume. Printer and Spoolman connections are managed here. The bootstrap file still configures LAN access and control policy. Back up the data volume; saved API keys must be protected like other host secrets.
