Printer SDK – External Receipt Printing Made EasyPrinter SDK – External Receipt Printing Made Easy
Enabled quick integration through a clear and simple SDK interface
Removed the need for app developers to handle complex, printer-specific details
Provided consistent receipt output across different printer models
About the Project
To support receipt printing as a part of the mobile payment flow, we developed a modular Printer SDK for both iOS and Android.
The SDK abstracts device-specific logic behind a simple, consistent interface, enabling receipt printing from external thermal printers without adding complexity to the app layer.
Business Challenge
The client needed to integrate receipt printing into their mobile payment system using a range of external printer devices, each with its own connection method and command set.
The solution had to detect available printers and manage device readiness, establish devices connection via different protocols and render receipts using consistent templates and assets.
Contributions
A Product Mindset Meets AI Discipline.
We designed and developed a modular Printer SDK that fits into the client’s payment flow. Our work included:
Custom plugins per printer model
Each plugin handles its own protocol, connection logic, and capabilities
Device discovery and readiness checks
The SDK automatically detects available printers and monitors their connection state
Template-based receipt rendering
Each printer plugin includes predefined layouts and static assets like logos or headers
Simple print interface
App-level logic only needs to pass structured data, while the SDK managed what and how to print
Reusable & Scalable Solution
Our solution was built for reusability:
- Each printer is encapsulated in its own plugin, allowing easy expansion
- The SDK can be reused across other apps that require receipts or other printing
- Designed to support new printer models or formats with minimal effort
Key Expertise
Deep integration with mobile payment workflows, including receipt handling and device state tracking
A strong focus on modular SDK design that scales across apps and platforms
