Rongta Portable Printer F81 - Inkless Thermal Wireless for Phone & PC

In this review of the Rongta Portable Printer F81, the bottom line is clear: this tiny, inkless thermal printer is best for users who need lightweight, on-the-go printing from phones, tablets or a laptop via USB. It stands out for portability and a simple app-driven workflow that gets documents from phone to paper quickly. While print quality varies with thermal paper and some users reported blank pages, the F81's ease of setup and support for common file types make it a practical choice for travel, receipts, quick drafts, and simple office tasks.

Key Features

• Wireless pairing: Bluetooth and WiFi allow phones and tablets to connect in seconds using the SoPrint app for fast mobile printing.
• PC compatibility: A USB driver and cable let Windows and Mac laptops print directly when Bluetooth is not available.
• Multiple file support: Prints Word, PDF, TXT, Excel and images so common document types work without conversion.
• Paper size flexibility: Supports 8.5in US Letter and other sizes such as A4, B5 and A5 to handle office and travel needs.
• Ultra-light design: At about 0.99 pound and compact dimensions, it fits in a bag for convenient mobile use.
• Quiet operation: Upgraded motor keeps noise below 60dB so printing is unobtrusive in public spaces.

Who It's For

The Rongta F81 is aimed at travelers, small business owners and remote workers who need occasional hard copies without carrying a full-size printer. It suits people who print receipts, itineraries, quick drafts or images while on the road and value handheld portability and simple phone-based printing via the SoPrint app.

It is not ideal for those who require high-resolution, long-run document printing or who prefer regular paper and ink. Users who rely on Linux or Chrome OS should look elsewhere since those platforms are not supported, and laptop Bluetooth printing is not available.

Pros & Cons

Pros

• Very portable and light, making it easy to carry for travel and field work.
• Simple mobile workflow with the SoPrint app and fast Bluetooth/WiFi pairing.
• Supports common document formats and multiple paper sizes including US Letter.
• Quiet printing suitable for libraries, cafes and meetings.

Cons

• Print quality is mixed and depends heavily on thermal paper brand and surface; some users report blank prints.
• Laptops cannot connect via Bluetooth and require the USB cable and driver for PC printing.
