You have the Fi-1000 machine and you print:
-labels
-envelopes
-paper bags
-carton boxes
-napkins
The ink costs between 120 and 180 EUR per 230 ml cartridge (which means around 500 EUR per liter or more) — a bit too high for you.
Yes, this is a long-term HP strategy: cheap hardware, expensive cost per copy.

The Fi-1000 is basically a larger version of the PageWide printhead, which you can also find in desktop printers.
You cannot buy ink freely on the market, because HP uses DRM technology.

HP has developed a solution for small industrial businesses and granted licenses to several partner companies to manufacture printers based on their technology:

• Neuralabel (USA)
• Boxmaking Machinery GmbH (Germany)
• TicabPrint (Poland)
• Rollenco (Netherlands)
• AstroNova (USA)
• iJet Color Printware (USA)
• Postmark (USA)
• SmartJet (Italy)
• and a few others, mostly resellers that rebrand these machines.

This machine is great for small orders and samples. However, printing more does not necessarily make it cheaper. Digital printing technology has a fixed cost per copy, so even with higher volumes, the cost per print remains roughly the same.

To reduce ink costs, we developed our main solution — InkBags.
This solution replaces the main engine of your printer with our engine and our RIP software.
By switching to our solution, your ink cost decreases by a factor of 7.
So if you currently spend 15,000 EUR per year on ink, you would spend only around 2,100 EUR.
We also supply ink and can provide new printheads when needed.
