No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.How does print quality compare to the genuine HP 30X? The 30X is engineered to match the OEM cartridge’s particle size, charge profile and toner densities so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.Do I also need the HP 32A imaging drum? Yes, eventually. These printers use a two-piece design: the 30X toner cartridge and a separate HP 32A (CF232A) imaging drum. The drum lasts roughly 23,000 pages, so most users replace it once for every six or seven high-yield toner cartridges.What is the difference between the 30X and the 30A? Same printers, different capacity. The 30X yields roughly 3,500 pages against the 30A’s 1,600, which makes it the cheaper option per page for anything but very light printing.How fast will my order ship?
