Operate a small internet business so print packing slips, postage, etc. Don't use a lot of ink but when I need it, I need it. Ink Technologies provides a very good product for a reasonable price. The only time I had a problem, they came up "Aces" and solved it. Good product at a good value. Easy website to navigate and fast service.

Great value for HP compatible ink cartridges. The name brand for my printer is now so expensive that I would have to buy a new printer if not for Ink Technologies. So they save me money in two ways, the price of the ink and not having to replace a working printer.I would recommend your company to everyone I know who needs printer cartridges.

    Difference between Compatible, Remanufactured, and OEM Products

    OEM (brand name) cartridges are provided by the manufacturer of the printer, such as HP, Dell or Brother. Pricing for brand name cartridges is frequently much higher than for non-brand cartridges, typically ranging from 2–5 times higher.

    Compatible cartridges are made from brand new components, provided by a non-OEM manufacturer.

    Remanufactured cartridges are refurbished OEM cartridges that have been inspected, repaired, cleaned and refilled.

    Compatible and remanufactured cartridges both have color and page yield comparable to the brand name product at typically much lower cost, and are backed by our 6-month quality guarantee and 1 year defect warranty.

    Please see our blog article for more info (opens in new window).

    Warranty for Compatible/Remanufactured Products

    Based on our 100% Satisfaction Guarantee, Ink Technologies will accept returns of compatible or remanufactured ink and toner cartridges for full credit if the returned product has a valid return authorization number and is received in our warehouse within 6 months of the original shipping date. If there is a confirmed print quality issue, only 1 set of opened products will be accepted for credit returns, and only if less than 30% of the ink or toner has been used.

    Ink Technologies will replace defective compatible or remanufactured products free of charge if the products are returned within 1 year of the original ship date, and provide a return shipping tag for return of the product.
