Although not a color printer, I have an HP Laserjet I bought back in 1994 and still is going on strong. I guess "they don't make them like they used to". I do know that every time a color printer is turned on there is quite a bit ink being used. So, you can turn that printer on and off and run out of ink before printing a single page. Therefore, I never turn off my color printer.
That was my thought a while back - until I read something to the effect that leaving a printer always on will cause the ink in the print head to dry and thereby clog the print jets.
I had exactly that experience with an old HP printer I bought, oh, 30-35 years ago. Haven't left a printer on since.
Of course, that was a long time ago, and printer technology has improved by galactic leaps since. But it seems to me that, given the way these companies operate, as detailed in the video, they might not be likely to make improvements that will decrease ink usage.
I also tried refills some years ago, and discovered that, while this does work, and does save money, the print quality tended to decrease with each refill - I was using a printer whose cartridges contained the print head. The decrease in quality was noticeable enough that I dumped the refills.
Nowadays, I use an Epson SureColor P800 - wide format, roll-capable, uses Ultra HD pigment-based inks - eight cartridges in all, but not all eight are always used. The printer switches between Photo Black and Matte Black, depending on the paper surface used - switching is automatic, and does use a small amount of ink. The P800's cartridges retail for about $51 each, but they are 80ml capacity, so they last a good while.
I turn the printer off between uses.
