continuous ink supply system

A Continuous Ink Supply System (CISS) has long become more than just a convenient add-on for an inkjet printer — it is a real financial lifesaver for anyone who regularly prints large volumes of documents, photos, or educational materials. When it comes to saving money, many users are surprised: is the system truly as profitable as manufacturers promise? The answer is clear — yes, but only if we look beyond surface-level claims and evaluate real calculations and long-term usage. A Printer Upgrade That Helps You Save on Ink The traditional printer model based on original cartridges involves significant ongoing expenses. One set of cartridges for popular printer brands such as HP, Canon, or Epson costs between €40 and €70, depending on the type and number of colors. At the same time, a single cartridge typically prints 150–300 pages. With simple calculations, we can estimate that the cost of printing one page ranges from €0.15 to €0.25 — and even more when printing color photos or presentation materials. For a home user, this may still be acceptable, but for an office or school printing hundreds of pages each month, these expenses quickly become excessive. With CISS, the situation changes dramatically. The system consists of external reservoirs connected to the printhead through ink tubes, allowing ink to be used from large refillable containers. The price of a CISS kit is usually €60–€90, which is roughly the same as just one set of original cartridges. However, once installed, the system pays for itself after the first or second refill. Savings in Black-and-White Printing Let’s consider black-and-white printing as an example. One 100 ml bottle of ink costs about €7 and allows printing approximately 2,000 pages of text. Meanwhile, an original black cartridge for the same price typically lasts for only 200–250 pages. The tenfold difference speaks for itself: the printing cost per page with CISS is around €0.0035, while with a cartridge it is about €0.15. Therefore, even with a modest print volume of 1,000 pages per month, the user saves approximately €146 monthly, which equals over €1,700 per year. What About Color Printing Benefits? For color printing, the savings are even more noticeable. A set of four CMYK ink bottles (100 ml each) costs around €25–€30. This amount is enough to print up to 7,000 pages of standard color documents or about 1,000 A4 photos. With original cartridges, printing the same volume…
