Recently, Xiamen Lujiang Technology Co., Ltd. (hereinafter referred to as Lujiang Technology) has been shortlisted in Fujian Province’s 2026 Provincial List of Innovative Digital-Economy Enterprises and awarded the title of “Gazelle-level Enterprise”.
It is reported that Lujiang Technology obtained the title of “National High-Tech Enterprise” in 2021. In 2023, it was included in the roster of “Innovative Small- and Medium-Sized Enterprises” and awarded the honor of “Xiamen Specialized, Refined, Differential & Innovative Enterprise”. In December of the same year, it was recognized as an entrepreneurial enterprise under the “Double-Hundred Talent Program” for leading-talent entrepreneurs. Up to now, the company has held the titles of High-Tech Enterprise and Specialized, Refined, Differential & Innovative Enterprise for consecutive years.
Growing from Scratch: Securing First-batch Customers through Independent R&D
Founded in 2019 in Xiamen, Fujian Province, Lujiang Technology was launched by the team led by Cai Jia’an at Xiamen Software Park to venture into the thermal-printer industry. Xiamen hosts a dense cluster of thermal-printer manufacturers, including established industry leaders and numerous small-to-medium players. The team decided to start with software development and build its mobile application independently. After months of development, its debut app “Dingdang Tong’xue” was officially launched in early 2020.
Market research conducted by the team revealed that competing thermal-printer software on the market mostly charged users for the error-question erasure feature. After internal deliberation, the team opted to release this function free-of-charge.
In 2020, the company rolled out its first compact printer, the “Dingdang Tong’xue” error-question thermal printer. This 2-inch thermal printer entered the market with its complimentary error-question erasure capability, winning its first-batch customers and achieving solid market traction.
Deep-rooted Expertise: Surging Patents and a Stream of Accolades
In its early days, the founding team maintained a clear view of its strengths and limitations. As a startup short on capital and manufacturing facilities, full in-house production of thermal printers posed major challenges. Nevertheless, the team possessed strong capabilities in software development and structural design. Advancing software features and hardware structures for thermal printers became its key breakthrough strategy. Focusing on portability as its core product differentiator in the thermal-printer segment, the company kept iterating both software and hardware. By 2020, the company had filed more than 20 patents.
On specific technical fronts, to address the issue of roll-paper shifting inside the paper compartment for multi-width paper rolls, the team developed a utility model patent for a “high-adaptability paper-compartment mechanism”. Movable limiting structures secure roll-paper positions while improving ease-of-use.
Conventional thermal printers carry a risk of user injury from accidental contact with the paper cutter. To mitigate this hazard, the team engineered a safety mechanism: when users press the operating component, the cutter and paper-pressing element extend together and are flexibly enclosed, greatly enhancing operational safety.
As output devices, thermal printers frequently run continuous print jobs. Maintaining stable performance under heavy-load continuous printing represents a critical challenge for manufacturers. Through intensive technical research, the team invented an invention patent for batch parallel printing built on fault prediction and load balancing. By splitting print tasks, building fault-prediction models, and recommending optimized print sequences for different print jobs, the solution boosts printer stability and service life.
To date, Lujiang Technology has been granted a total of 77 published patents and 34 software copyrights. Alongside its growing patent portfolio, the enterprise has earned successive honors. For three consecutive years, it has been certified as a National High-Tech Enterprise, a Specialized, Refined, Differential & Innovative Enterprise, and a Technology-oriented SME, gaining high-level recognition from national authorities. The company states that R&D always sits at the core of its development strategy.
Rapid Expansion: From Contract & Joint-venture Manufacturing to In-house Factories
Fast-growing patent output placed higher demands on product manufacturing quality. Meanwhile, offline retail clients across Europe and North America set strict requirements for product quality and fine craftsmanship. Coupled with soaring sales volumes, the original capacity from outsourced and co-operated factories was no longer sufficient to fulfill incoming orders.
Driven by its rapid business growth, Lujiang Technology made a pivotal strategic decision in 2025: building its own manufacturing facility.
Site selection for the new factory was completed by the end of 2025.
January 2026: Two production lines went into official operation.
June 2026: The enterprise relocated to new office premises, establishing dedicated departments including the R&D Center, Sales Center and Quality Laboratory.
August 2026: Production lines expanded to seven; semi-automatic manufacturing equipment was introduced to upgrade from fully manual to semi-automated production workflows.
October 2026: The SMT dust-free workshop was officially put into service.
Within merely one year, the factory was built from the ground up. Headcount exceeded 300 employees, and the plant covers an area of over 20,000 m². The company has basically achieved independent in-house manufacturing capacity.
Public definitions note that Gazelle-level enterprises feature robust rapid-growth capacity. Powered by technological, business-model or product innovation, they maintain annual revenue growth rates of no less than 20% for at least three consecutive years. Another defining trait is high operational agility: thanks to their relatively moderate scale, they can swiftly adjust strategies in response to market shifts.
Though a young enterprise, Lujiang Technology entered the thermal-printer sector with a focus on portability and has secured a distinct niche both in Xiamen and across China’s thermal-printer industry.
Brand Recognition: User-centric Product Development
Lujiang Technology consistently prioritizes product innovation and develops solutions based on real-world user requirements.
The C50 water-transfer printer boasts a rounded compact form and supports three printing modes: thermal, water-transfer and tattoo-stencil printing. Positioned within the creative children’s stationery category, it has sold more than 500,000 units on overseas online marketplaces including Amazon, Mercado Libre and Temu following its launch in European and American markets.
Its A4 thermal-printer series features portable compact dimensions, strong performance and compelling price competitiveness, hitting monthly sales of 100,000 units across overseas brick-and-mortar retailers and e-commerce channels.
During new-product development, the team adheres to the philosophy of “research first, development second”. It optimizes and fine-tunes product functions and performance after fully mapping user pain points before launching products that meet genuine market demands. Its goods are now exported to more than 190 countries and regions worldwide, serving dozens of domestic and international brand partners. Lujiang Technology is continuously building out its global sales network and after-sales support system.
Against the backdrop of fast-evolving and widely-adopted AI technology, Lujiang Technology integrated AI capabilities into thermal printers in 2026 by releasing the AI50 thermal printer. Highlighting one-tap AI voice-powered image generation, it brings artificial-intelligence innovation to the printing-device industry to elevate user convenience and overall experience.
According to the company, sharp market insight and sustained scientific-technological innovation constitute key factors behind its selection as a Gazelle-level Enterprise.
Looking Ahead
Being named a Gazelle-level Enterprise stands as recognition of Lujiang Technology’s development milestones, as well as momentum for its future advancement. The thermal-printer industry in Xiamen is highly competitive. Established industry leaders have embarked on diversified development, with core players commanding complete industrial-chain resources. Lujiang Technology still faces substantial challenges to consolidate its market position. Moving forward, the company will keep advancing along its three core pillars: technological innovation, deep engagement in vertical market segments, and adoption of cutting-edge technologies. It will continue delivering high-quality products for global users and demonstrating its market value.
