As information flows continue to grow across all areas of life, printing volumes are increasing as well, making the cost of consumables a major concern. Is it possible to print a lot, print well, and still save money? The answer is yes — with a Continuous Ink Supply System (CISS). This technology has long been popular among offices, educational institutions, and even home users who print large volumes of documents and images.
What Is a CISS and How Does It Work?
A CISS is an external system of ink tanks connected to the printer via airtight tubes, delivering ink directly to the cartridges. Instead of constantly buying and replacing expensive original cartridges, users have access to large refillable ink reservoirs.
The principle is simple: the tank sits next to the printer, and the ink remains at atmospheric pressure. When the print head uses ink, the system automatically supplies more, ensuring continuous, interruption-free printing.
Cost Savings
The primary advantage of a CISS is the significant reduction in printing costs.
A standard inkjet cartridge typically costs 300–800 UAH and prints 200–400 pages. On average, a single page costs 1–2 UAH.
A CISS uses bottled ink, which costs around 150–250 UAH per 100 ml. This amount is enough for several thousand pages. As a result, the cost per page drops 15–20 times — down to just 0.10–0.20 UAH.
For example:
An office printing 5,000 pages per month would spend around 6,000–8,000 UAH using standard cartridges. With a CISS, the monthly ink cost drops to just 700–900 UAH.
The savings are undeniable — and particularly impactful at high printing volumes.
Print Quality: Does CISS Perform Worse Than Original Cartridges?
Many users worry that using alternative ink in a CISS might reduce print quality. In reality, print quality depends primarily on the printer itself and choosing the right ink.
Modern ink manufacturers offer products tailored to specific printer models:

This ensures:
- sharp, smear-free text;
- vibrant, saturated colors in photos;
- stable and accurate color reproduction.
For everyday document printing, the difference between CISS and original cartridges is practically invisible. For professional-grade photo printing, original inks may be preferable — but for most tasks, from office work to school assignments, a CISS provides the best balance of cost and quality.
Additional Benefits
Beyond cost savings, a Continuous Ink Supply System offers several other advantages:
- Convenience — no need to constantly monitor ink levels inside cartridges or run out to buy replacements.
- Eco-friendliness — significantly fewer disposable plastic cartridges end up as waste.
- Stable printing — no printing interruptions caused by a cartridge running out mid-task.
Conclusion
A Continuous Ink Supply System is an efficient solution for anyone who values cost savings and practicality without compromising print quality. It transforms a standard inkjet printer into a highly productive tool capable of printing thousands of pages at minimal expense.
For offices, schools, print shops, and even home users who frequently print text or photos, a CISS delivers convenience, performance, and substantial financial benefits.
