Spot on

Previously always used the proper cartridges, this time I went for cheaper compatible ones instead, I'll never make that mistake again. I've always had really clean sharp images, but with these, I get bits and specs all over the sheet, ruining the overall image of the work and looking totally unprofessional on my documents for work. I've only printed 20 or so pages so far, but all of them have this on them. Can't afford to throw them away, but would if I had money to spare.
