I have a Brother laser printer which is used for almost everything, and a Canon inkjet for the occasional color print.
I’m pretty sure my Canon inkjet uses more ink when idle than when I occasionally use it to actually print something. Quite sad.
I do wonder where it all physically goes tho. After years of seeing my cheapo cartridges just “evaporate” whatever reservoir the printer has for cleaning the heads and purging ink must be well and fully saturated at this point?!
Yes and the printer has an internal counter keeping track of how much it has dumped into the sponge. After a long time it will stop and require disassembly of the printer and a reset procedure to rectify this.
Mine doesn't, some nozzles clogged every time I wanted to print (infrequently, sometimes months). Now I'm printing a test page every week to prevent that (maybe should add a cron job).
A contributing factor could be that the best-before date on the bottles is in the past. Though I have no idea how that date would matter for filling up, and no idea how to observe it after the ink is in the printer and the bottles disposed of.
