Quality and economical printing is made possible with this premium compatible cyan toner to suit selected Hewlett Packard HP LaserJet Pro 300 and LaserJet Pro 400 colour series printers and multifunctions (see list). High quality manufacturing standards guarantee you optimal print quality plus the same number of pages for a fraction of the OEM's cost, thus representing excellent value and a true alternative as a OEM replacement. Designed to save you money, just like OEM cartridges our premium compatible laser print cartridges use real polymerized toner, which produces a consistently smaller, circular shape that improves print resolution, increases toner yield and decreases cost per page. Plus, for your complete peace of mind, our premium compatible laser print cartridge comes with a full Replace, Refund or Credit guarantee if you aren't entirely satisfied. Competitive Pricing – Great Savings!
