What is StarIO.Online?
StarIO.Online is a fully managed cloud printing service from Star Micronics that lets developers send print jobs and manage printers through a single API, without hosting or maintaining their own server.
It is built on top of Star’s CloudPRNT technology, but instead of a business or software provider hosting their own CloudPRNT server, Star hosts and manages the infrastructure for them.
In short: CloudPRNT is the protocol, and StarIO.Online is Star’s own hosted service built on that protocol.
How is StarIO.Online different from CloudPRNT?
CloudPRNT is an open protocol. To use it, a developer typically needs to build and host their own server that follows the CloudPRNT specification.
StarIO.Online removes that requirement. Star hosts the server infrastructure, monitoring, and uptime, and developers connect through a pre-built REST API instead.
This means:
With standard CloudPRNT, the business or ISV is responsible for hosting and maintaining a server. With StarIO.Online, Star Micronics hosts and manages the server, and the developer calls a ready-made API.
Both ultimately use the same underlying CloudPRNT technology to communicate with the printer.
Who is StarIO.Online for?
StarIO.Online is designed mainly for independent software vendors (ISVs) and POS software developers who want to add cloud printing to their platform without building backend infrastructure.
It is also useful for businesses managing printers across multiple stores or locations, since devices can be monitored and controlled centrally from one dashboard.
What can I do with StarIO.Online?
With StarIO.Online, developers and businesses can:
Send print jobs to any CloudPRNT-compatible Star device with a single API call, monitor device status in real time (such as paper out, offline, or cover open), receive webhook notifications for print job results, barcode scans, and new device connections, manage printers individually or in groups across single or multi-store environments, and print directly via email for simple use cases, without needing an integration at all.
Which printers work with StarIO.Online?
StarIO.Online works with Star’s CloudPRNT-enabled devices, including the mC-Label series, mC-Print series, and TSP100IV.
Compatibility depends on the specific model and firmware version. Check the StarIO.Online product page for current supported devices.
Do I need to host a server to use StarIO.Online?
No. This is the main difference from a standard CloudPRNT integration. StarIO.Online is entirely cloud-based and hosted by Star Micronics, so there is no server to install, configure, or maintain.
How do I set up a printer on StarIO.Online?
Setup depends on the printer and connection method, but Star’s newer “Easy Deployment” process is designed to simplify it:
Once the printer is connected to the network, the printer’s serial number is entered into the application, a brief printer operation is performed, and the device automatically connects to Star’s cloud infrastructure. A confirmation printout verifies the connection was successful.
This replaces the older process of logging into a printer’s web interface to manually configure server URLs.
Is StarIO.Online secure?
Yes. Devices connect outbound to Star’s cloud platform rather than accepting inbound connections, which avoids the need to open firewall ports or maintain certificates on individual printers. Access to the API is controlled through account-based API keys.
How much does StarIO.Online cost?
StarIO.Online is available with a free trial period, followed by subscription-based pricing. (Confirm current trial length and pricing tiers before publishing, as these are subject to change.)
What is the difference between StarIO.Online and StarIO (the SDK)?
These are two different things despite the similar name.
StarIO (sometimes referred to as the StarIO SDK) is a local software development kit used to communicate directly with a printer from an app on Android, iOS, Windows, Linux, or macOS.
StarIO.Online is a cloud-hosted service used to send print jobs and manage devices remotely over the internet, with no local SDK integration required for printing itself.
StarIO.Online is part of Star Micronics’ cloud services, giving software developers a way to add cloud printing and remote device management to retail, hospitality, and online ordering platforms across Europe, the Middle East, and Africa without building backend infrastructure.
