Buying HP products is bad investment.

I only had the chance to two of their inkjet printers and one of their office laser printers, plus an elitebook laptop. In short, all of them suck.

Much better (to me, the best) alternatives, that I can safely say are good investments: Canon for inkjet printers, ThinkPad T and P series for laptops. Those are quality products. Unfortunately I don’t have any experience with other office laser printers, so I cannot recommend one.

Edit: specified which series of ThankPads are still good.
