Long. Printers are pretty complicated machines, because they have to work with a natural product that shrinks, expands, folds, rolls itself up and sticks to other pieces of paper. I once heard a printer engineer explain that they use small puffs of air to lift the paper, but because there’s also heat involved in the printing process that the paper sometimes rolls itself up or expands which causes jams etc. And I’m sure there’s more going on.
Which isn’t to say that HP aren’t bastards.
Same here. But sadly too many people were swayed by the populist parties and their ‘this one trick will fix everything’ rhetoric.
