Exact routing
Send work to a queue configured for a site, printer, tray or paper format.
Cloud printing for real operations
Nebulas Cloud Printing connects your business software to local queues. An authorised client group keeps the same destination available: the active node prints on the exact queue and a standby takes over automatically when needed.
✓Signed x64 MSI · Java runtime included · per-user automatic start
In short
It is a service that sends documents created by a cloud application to a physical office printer in a controlled way. Multiple authorised clients can share an active/standby group so one workstation does not interrupt the queue; no AWS credential is installed on the PCs.
How it works
The gateway and client coordinate every stage, so users do not have to download, locate and reprint PDFs manually.
The application creates the document and selects the destination local queue.
The job remains tenant-isolated and is available only to an authorised device.
The gateway gives work only to the group leader, which downloads the PDF and uses the exact queue. An eligible standby takes over if the active node becomes unavailable.
The PRINTED, FAILED and DELIVERY_UNKNOWN states close the loop and make the outcome verifiable.
Features
Exact routing and automatic failover without exposing the local network to inbound connections.
Send work to a queue configured for a site, printer, tray or paper format.
Two or more authorised clients share a logical group; priorities select the preferred workstation.
The gateway keeps one leader and transfers work to an eligible standby when the active node is no longer available.
Jobs not yet sent to the spooler return to pending; an uncertain physical outcome is never reprinted automatically.
Heartbeats, leadership, completion and DELIVERY_UNKNOWN states show what happened.
The signed package starts with Windows and includes Java 17, with no separate install or elevation.
Secure by design
The device is approved in the browser after a recent login and strong MFA. Grants are renewable and revocable; printing stops when the user, licence or workstation is no longer valid.
Each workstation receives a dedicated grant after user approval.
Windows DPAPI, macOS Keychain or Linux Secret Service protects the renewal credential.
The client uses only the authenticated Print Gateway to register, claim work and report results.

Get started
Run the package on every intended workstation. For failover, each one must see the same local queues.
Complete login and MFA in the browser, then approve each PC in the group separately.
In the Portal, assign the same group, set priorities and confirm that queue names match on every client.
Compatibility
For failover, every group member must expose the same queue names. Configure trays, media sizes and other hardware preferences in the operating system.
Frequently asked questions
What you need to evaluate, install and operate Nebulas Print Client.
It is the desktop agent that securely connects Nebulas Cloud Printing to print queues installed on a local workstation.
No. Native packages include the Java 17 runtime required by the application.
No. The client starts outbound HTTPS connections to the Print Gateway and needs no inbound cloud connection to the LAN.
The current version processes PDF documents and sends each job to the local queue selected by the business application.
The client pauses its loop, applies controlled retries and resumes automatically when the service is reachable.
In the Nebulas Portal, assign two or more clients to one group and set their priority; the lower number is preferred. The gateway gives jobs to one leader, and an eligible standby takes over automatically when that leader is unavailable.
If a client stops while downloading, the job returns to pending when its recovery lease expires. After submission to the spooler, an uncertain result becomes DELIVERY_UNKNOWN and is not automatically reprinted, avoiding possible duplicates.
Yes. Device grants are checked periodically and can be centrally revoked; revocation stops polling and heartbeat activity.
For the first version, configure one operating-system queue for each required combination and route the job to that exact queue.
