Sell me a printer that doesn't lock me in, then.
Because it's not a business model I would ever want to participate in. Same as if Ford told me that I have to use their airpumps to blow up my tyres and that they can set the price how they like.
That said:
- I haven't used inkjets / ink, personally or professionally, for nearly 20 years now. Why on earth would anyone?
- I haven't needed to upgrade my personal printer since 2000. It's a Samsung mono laser (parallel port!) and it just keeps going. (Alright, I need an Intel NetportExpress - with a 386SL chip inside! - to network it, and a driver that only CUPS has, but it works) The last consumable replaced was a paper feed roller that had worn down from a thick toothed gear-like roller to a tiny smooth pipe... I honestly didn't think it was the same part when it arrived and I needed to change it out. The toner, I just fill its refillable toner cartridge from whatever toner I have lying around.
- I haven't *needed* to print, at home, for over a decade. At work, my print account is the lowest of every user, despite being the IT manager. I only print for other people, not for me.
And much of this is because of printer manufacturer's business models, and a changing world. My books aren't paper anymore. My flight tickets aren't (flew with daughter with electronic tickets, faster, no problems, and we each had a backup of the other's tickets). Tax returns are online. My pension statements are online. My payslips are online. Every single one of my utilities are online. The stuff that's actually on paper now is the stuff that refuses to upgrade because they're luddites. The people who demand paper now are people who haven't got into the 20th century, let alone the 21st.
And if I do ever want some fancy photos printed? Next-day online service with proper dye-sub printers, or take them into a kiosk in a supermarket / Boots, and get them within minutes. Why on earth would I print them at home with stupendous ink costs on either cheap paper or very expensive photo paper, and risk them fading over time? In fact, the last set of photos that I wanted to keep were turned into 35mm slides and put into a Slidelight - which is basically a long, thin, white illuminated surface that you hang on your wall. They look incredible. And they all came from JPEGs.
Your business is dying already, and you think the way to keep it is to put a strangehold on the few naive customers you have left that were willing to part with stupendous money per page/photo?
