1. What Is the Internet Interface?
Official Definition
The Internet interface is a cloud-service task offline-scheduling solution provided by Ruifengcai cloud printing.
It is a cloud-service task offline-scheduling solution: a third-party platform (web store, app, mini-program, etc.) calls the interface to submit a job to the cloud scheduling center, which drives the printer through the client software to complete printing. It turns complex hardware operations into a stable, visible cloud service, solving the traditional print problems of manually configuring drivers, standing by the machine, lacking progress tracking, and losing jobs on disconnect.
Plain Explanation
In short: Ruifengcai cloud printing turns complex hardware printing operations into a stable, visible, and easy-to-manage cloud service.
You don't need to know how the printer connects or is driven — you only call a simple interface, and the cloud handles the rest.
What Problems Does It Solve for You?
| Problem | Traditional Approach | After Using the Internet Interface |
|---|---|---|
| Printer connection | Manually configure drivers and connect ports | No need to care — handled automatically by the cloud |
| Task management | Stand by the printer in person | Submit remotely, print automatically |
| Status tracking | No visibility into print progress | Real-time callback, fully visible |
| Offline handling | Jobs lost on disconnect | Cloud staging, resume printing after reconnect |
2. Workflow (Done in 5 Steps)
One-Click Submit
Your application (store, mini-program, ERP, etc.) submits a print job to the cloud through a simple interface — no need to worry about where the printer is or how it connects.
Cloud Scheduling
The cloud platform acts as an "intelligent scheduling center," automatically assigning the job to the queue of your designated printer.
Smart Dispatch
The job is stably delivered to the client software beside the printer. Even if the printer is offline at the time, the job is staged in the cloud and automatically reprinted once it comes back online, ensuring the job is never lost.
Offline Printing
Supports offline job dispatch — the printer client software automatically pulls all pending print jobs from the cloud after coming online.
Status Callback
Every status step — print success, failure, etc. — is returned to your system in real time through the callback interface, fully visible and traceable.
3. Core Features
| Feature | Description | Benefit to You |
|---|---|---|
| Cross-platform & easy integration | Quick onboarding through a standardized API, eliminating the complex work of directly managing and driving various printers | No need to study various printer drivers — one interface handles them all |
| High reliability | Relies on the cloud queue and offline-resume capability to completely solve job loss and disorder caused by network or device issues, ensuring business continuity | No fear of disconnects or power loss — jobs are never lost |
| Process visibility | Real-time access to job execution status, giving full clarity on each order's progress for internal management and accurate feedback to end users | Always know print progress and tell customers the order status |
4. Typical Use Cases
Remote & Chain Operations
Applies to: Industries such as e-commerce, advertising/print graphics, and personalized customization that need centralized order intake with nearby printing across locations / multiple stores.
Examples:
- You take orders in Beijing; stores in Shanghai and Guangzhou print nearby.
- Headquarters manages centrally; branch stores execute print jobs automatically.
Online Business Enablement
Applies to: Your own web store, website, mini-program, or app.
What it can do: Provides a closed-loop capability of "one-click order, automatic printing."
Examples:
- A user orders a customized phone case in the mini-program.
- The order is automatically sent to the printer.
- After printing, it ships directly.
Management & Audit
Applies to: Enterprises, government, and chain stores.
What it can do: Meets the need for centralized management, data statistics, and audit trail of print jobs.
Examples:
- Count how many orders were printed each day.
- Query the print record of a specific order.
- Export print data for reports.

6. Frequently Asked Questions (FAQ)
Q1: What is the difference between the Internet interface and the LAN interface?
A:
| Comparison Item | LAN Interface | Internet Interface |
|---|---|---|
| Network requirement | Must be on the same LAN | Remote-capable, supports the Internet |
| Status callback | Not supported | Supported — real-time job status |
| Offline capability | Not supported | Supported — cloud-staged jobs |
| Operations management | Not supported | Supported — remote management |
| Use case | Internal process automation | Remote management, e-commerce integration |
Recommendation: If you need remote management or e-commerce integration, choose the Internet interface ✅
Q2: What are the requirements to integrate the Internet interface?
A: You must meet the following conditions:
- A working UV printer.
- Cloud-printing client software installed.
- Development capability to call the API.
- Use the HTTPS protocol (security requirement).
Q3: If the printer goes offline, will the job be lost?
A: No. The Internet interface supports offline-resume printing:
- The job is staged in the cloud.
- The printer automatically pulls the job after coming online.
- Ensures the job is never lost.
Q4: Is the status callback mandatory?
A: Not mandatory, but strongly recommended:
- Without it: you must manually check status on the service provider's platform.
- With it: receive print status in real time, with higher automation.
Q5: Can one account connect multiple printers?
A: Yes. The cloud supports multi-device management:
- You can specify which printer a job is sent to.
- You can set up printer queues.
- Supports multi-store, multi-location deployment.
Q6: What if an interface call fails?
A: Common causes and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Signature error | Incorrect signature generation | Check the signature algorithm and parameters |
| Network error | HTTPS not used | Ensure the HTTPS protocol is used |
| Parameter error | Inaccurate material-size measurement | Re-measure and pass parameters as required |
| Device offline | Printer not online | Check network connection and device status |
Q7: What types of products can be printed?
A: Multiple product types are supported:
- General products (Desktop edition)
- Badge (吧唧), coin, fridge magnet, commemorative coin, acrylic board, etc. (Kiosk edition)
The specific product types supported depend on the client software version you use.
Q8: How do I query print job status?
A: Two ways:
- Active query: call the "Query designated print job" interface.
- Passive receive: configure a callback address; status is pushed automatically on change.
Q9: Can a submitted print job be canceled?
A: Yes. Two cancellation methods are supported:
- Cancel a designated print job — cancel a single order.
- Cancel all print jobs — clear the current queue.
