HP has recently settled a lawsuit accusing it of defrauding ink users. The three specific charges were that some HP printers used color ink when printing black and white pages without letting users know or letting users change that setting, that HP printers gave false "low" readings on cartridges so users would replace them more quickly, and that some HP ink cartridges stopped working after a certain period of time even if they had ink left. Those charges matched my own experiences with recent HP printers, which was why last year I junked my HP's and replaced them with Cannon printers, and why I won't be buying any HP products again for a long time.
The results of the lawsuit? HP agreed to pay $5 million to consumers…in the form of $6 coupons for more HP ink.
