HP Instant Ink is “ink as a service”
This<p>> Requiring frequent "calibration" printouts that use vast amounts of ink<p>I use my personal printer once every 2 months, on average, and every single time it prints the calibration page.<p>It would make much more sense from a UX point of view if it just asked if I want to calibrate instead of forcing me to waste ink, paper, time and patience in the process.
