Printly is an application designed to provide a convenient printing service for college students. It allows users to upload their documents, customize them as needed, pay for the printing service, and collect the order from a designated store.

The application aims to streamline the printing process for students, eliminating the need to visit a physical print shop and reducing turnaround time. By leveraging technology, Printly provides an efficient and user-friendly solution for document printing.

The primary objectives of the Printly application are as follows:

- Provide a platform for college students to upload and print their documents.

- Enable document customization options such as paper size, color, and binding preferences.

- Facilitate online payment for printing services.

- Automate the order processing and tracking system.

- Simplify the document collection process from a designated store.

Printly offers the following key features:

- User registration and authentication.

- Document upload and storage.

- Document customization options (e.g., paper size, color, binding).

- Price calculation based on document specifications.

- Online payment integration.

- Order tracking and status updates.

- Store locator for document collection.

- Notifications for order status changes.

The system architecture of Printly follows a client-server model. The client-side consists of a web or mobile interface where users interact with the application. The server-side handles the processing and storage of user data, as well as integrating with external services.

The architecture includes the following components:

- Client Interface (Web or Mobile)

- Application Server

- Database Server

- Payment Gateway

- Document Storage

The client interface communicates with the application server through APIs. The server processes user requests, interacts with the database server for data retrieval and storage, and communicates with the payment gateway for payment processing. Document storage allows users to upload and retrieve their documents.

Printly utilizes the following technologies and frameworks:

- Frontend: Flutter (Dart), ReactJs

- Backend: Firebase

- Database: MySQL

- Payment Gateway: Razorpay

- Document Storage: FireStore

Printly supports the following user roles:

1. Student/User: The primary user role who uploads documents, customizes them, pays for printing services, and collects orders.

2. Admin/Store Manager: Manages the system, including document processing, order management, and store settings.

3. Guest: Unregistered users who can browse the system but cannot access certain features (e.g., order placement).

The user interface should be intuitive, responsive, and accessible. It should provide clear navigation for users to upload documents, customize print options, make payments, and track their orders. The interface should also display relevant information, such as order status, pricing details, and store locations.

The typical workflow for a user in Printly is as follows:

1. Register or log in to the application.

2. Upload the document to be printed.

3. Select customization options such as paper size, color, and binding.

4. Review the document specifications and calculated price.

5. Proceed to the payment page and complete the transaction using a preferred payment method.

6. Receive an order confirmation with a unique order ID.

7. Track the order status through the application, with updates on processing, printing, and ready-for-collection stages.

8. Receive notifications for any changes in the order status.

9. Visit the designated store to collect the printed document, presenting the order ID for verification.

10. Validate and collect the printed document from the store.

Printly's database schema includes the following tables/entities:

- Users: Stores user information (e.g., name, email, password).

- Documents: Stores document details (e.g., document ID, file path, user ID).

- Orders: Tracks order details (e.g., order ID, user ID, document ID, customization options, price, status).

- Stores: Manages store information (e.g., store ID, location, operating hours).

Printly exposes APIs for various functionalities, including:

- User authentication and registration

- Document upload and retrieval

- Order placement and tracking

- Store location and information retrieval

Detailed API documentation should be provided, including endpoint URLs, request/response formats, and authentication requirements.

Printly should incorporate proper security measures to protect user data and ensure secure transactions. Key security considerations include:

- User authentication and authorization

- Encryption of sensitive data (e.g., passwords, payment information)

- Secure communication using HTTPS

- Input validation and sanitization to prevent common security vulnerabilities (e.g., SQL injection, cross-site scripting)

- Regular security audits and updates to address emerging threats

Printly can be deployed on a cloud infrastructure or dedicated servers. Deployment considerations include:

- Setup of application servers and web servers

- Configuration of the database server

- Integration with cloud storage services for document storage

- Configuration of SSL certificates for secure communication

- Load balancing and scaling strategies for handling high user traffic

To enhance the functionality and user experience, potential future enhancements for Printly may include:

- Integration with popular cloud storage providers for seamless document import.

- Support for additional customization options (e.g., paper quality, finishing options).

- Mobile applications for convenient access and document uploads.

- Integration with third-party printing services for expanded printing options.

- Integration with popular learning management systems (LMS) for streamlined document submission.

Printly is a user-friendly application designed to simplify document printing for college students. By providing an online platform for document upload, customization, payment, and order collection, Printly aims to streamline the printing process and improve overall convenience for users.
