StarXpand™ SDK for React Native

Typically, mobile POS applications have been developed exclusively for each operating system (OS), such as iOS, Android and Windows. However, cross-platform development, which allows application programs to be developed with one set of source code in a single programming language for multiple operating systems, is gaining ground. As a result, cross-platform development is expected to become essential to application development in the future, due to its lower overall development and maintenance costs.

Responding to this trend, Star has developed StarXpand SDK, initially targeting React Native but scheduled to later include other native and alternative cross-platform environments, to help reduce the development time and maintenance costs associated with printer connection.  The SDK features a new StarIO10 framework that provides a number of advantages including asynchronous communication allowing print jobs to take place in parallel, lowering implementation costs and the possibility of bugs while improving code readability. As StarIO10 is emulation-free, one StarXpand document will work with any current Star POS / Mobile printer.



About React Native

React Native combines the best parts of native development with React, an in-class JavaScript library for building user interfaces. React Native can be used today in your existing Android and iOS projects or it can be used to create a whole new app from scratch. React Native is currently already being used in thousands of apps, such as Shopify, Facebook, Instagram and many more.  


About StarIO10

StarXpand™ SDK for React Native uses a new StarIO10 framework which includes multiple advantages including: asynchronous communication, an emulation-free design, human-readable command creation, faster printer search, and a logging function between the OS and printer. StarIO10 features log communications between the operating system and the printer, designed for debugging. This log feature can shorten analysis time when an issue arises, avoiding prolonged downtime and saving businesses valuable time and unnecessary cost.


Asynchronous Communication

StarIO10 features asynchronous communication, allowing print jobs to happen in parallel and meaning that developers do not need to write an asynchronous process. This can reduce implementation costs, reduce the possibility of bugs, and improve code readability.


Because StarIO10 is emulation-free, one StarXpand™ document will work with any Star printer, meaning there is no need to make any changes even if a printer is changed.

Human-Readable Command Creation

With human-readable command creation, StarIO10 allows users to create commands with a command builder. Next, human-readable intermediate commands and raw binary commands are generated, respectively. This process makes it easy to understand what data a printer receives, helps problem-solve, and means commands are reusable as a print format without emulation dependencies.

Faster Printer Search

Faster than ever, StarIO10 allows users to discover all devices in under second (10 to 300 milliseconds). This feature greatly improves search speed, especially for LAN printers.

Log Communications Between OS and Printer

StarIO10 features log communications between the OS and the printer, which is designed to be used for debugging. This log feature can shorten analysis time when as issue arises in the field, avoiding prolonged downtime and thus saving businesses valuable time and money.

Part of the Star Micronics Technology Portfolio

StarXpand™ SDK for React Native is just one of the many technologies offered by Star Micronics. Other solutions include CloudPRNT, which enables users to print to Star Micronics printers directly through a cloud service, and SteadyLAN™, which provides wired Ethernet service to devices connected to a networked printer via the Lightning or USB-C® cable.
