Photo Booth & Printing Management System
A custom Android solution designed to simplify photo selection, template composition, image adjustment, preview, and printing for a photography and photo booth workflow.
Development Completed
Client Delivery
Built around a real-world printing workflow.
The application brings photo selection, template-based composition, touch adjustment, preview, and printing into a dedicated Android workflow for photography and photo booth operations.
Admin and Staff share the same app, with access determined by role. Administrators manage staff accounts and monitor printing activity; operators run the photo-to-print path on site.
The Workflow
From folder selection to print—and activity recorded for Admin monitoring.
Compose
Select a pre-created print template.
Adjust
Position and scale the photograph using touch gestures.
Preview
Review the final template composition.
Send the completed composition through the Android printing workflow.
Track
Printing activity is associated with the staff account for Admin monitoring.
Key Features
Confirmed capabilities built for the client’s photo booth and printing workflow.
Role-Based Access
Admin and Staff authenticate in the same Android application, with available functionality determined by role.
Photo Folder Selection
Operators manually select a designated folder on the device where photographs have already been transferred.
Photograph Browsing
Browse selectable images from the chosen folder, pick a photograph, and change the selection before completing the workflow.
Template-Based Composition
Apply client-specific, pre-created print templates that define the fixed layout for the final composition.
Pinch-to-Zoom & Positioning
Scale with pinch-to-zoom and drag to reposition the photograph within the template’s designated composition area.
Preview Before Printing
Review the final template composition, return to adjustment if needed, then proceed to print.
Epson L8050 Integration
Print through Android’s printing infrastructure, supporting USB printing and IPP-based network printing to the Epson L8050.
Printing Activity Monitoring
Backend records printing activity by staff account so Admin can view individual counts and overall printing activity.
Admin + Staff
One application, two roles—customers are not direct users of the app.
Management & monitoring
- Create and manage staff accounts
- Manage staff login credentials
- View staff members
- Monitor printing activity
- View individual staff printing counts
- View overall / total printing activity
Photo-to-print workflow
- Login
- Select photograph folder
- Browse and select photographs
- Select a pre-created print template
- Adjust photograph (pinch-to-zoom, drag/reposition)
- Preview final composition

Solving the Printing Challenge
Reliable physical printing from the Android application was the major technical challenge.
Challenge
Reliable physical printing from the Android application.
Investigation
Explore direct USB/OTG communication with the Epson L8050.
Problem
Direct USB output was unreliable and produced garbled/corrupted prints.
Change
Redesign printing around Android’s native printing infrastructure.
Solution
Android printing integration, plus IPP-based network printing support.
The initial implementation explored direct USB/OTG communication with the Epson L8050. The resulting output was unreliable and produced garbled/corrupted prints.
Instead of retaining an unreliable approach, the printing architecture was redesigned around Android’s native printing infrastructure. The final implementation uses Android printing integration and also supports IPP-based network printing.

Outcome
The completed application provides the client with a dedicated workflow for selecting photographs, applying print templates, adjusting and previewing photographs, and printing them through an Epson L8050 printer. It also provides role-based Admin and Staff access and allows administrators to monitor staff printing activity and overall printing counts.
The project demonstrates the development of a real-world, client-specific Android application combining touch-based photo composition, role-based access, backend services, printing activity management, and physical printer integration.
