  • LD Remanufactured Black & Color Ink Cartridges for HP 21 & HP 22

    Q:

    are these cartridges a high yield or the same type I can buy in a retail store

    I have been buying a higher yield product and would like to continue. The picture looks like the regular retail lower yield. Do you have the high yield product and
    if so please include yield rates.

    • A:

      We do carry the high yield HP 54 black and HP 57 color cartridges. It would be best to confirm that your printer model takes these two items before placing an order. We would be happy to assist you if you need any help! Please feel free to contact us at 888-321-2552.

    • A:

      The remanufactured HP 21 and HP 22 are both standard yield ink cartridges. The page yield on both of these units are 190 and 165 consecutively. The page yield is based on the 5% industry standard. We sell the high yield cartridges as well, but it will vary depending on the printer's model number. Please give us a call at (888) 321-2552 so we can double check the compatibility and answer any other questions or concerns.

I like getting my ink from 4inkjets as it is easy, convenient and affordable. I also like their customer service as they handle your questions and problems with ease and will always replace anything that you have a problem with. The only problem is that the problems happen a little to often with cartridges not installing properly, they won't print or the printer won't recognize the cartridges, but as I said they are happy and quick about replacing them.

I used LD products​for printing in the past, which is my reason for choosing it for my printer again. The product worked like the brand name ones. I will choose and recommend it to friends.

Cartridge Comparison Guide
  • Cartridge Types
  • Ink & Toner Basics
  • Number of Pages & Shelf Life
Cartridge Type
Genuine or OEM (Original) Cartridges Remanufactured Cartridges Compatible Cartridges
Description OEM stands for original equipment manufacturer, meaning the cartridge was made by the same company that made your printer. Original brand cartridges are very reliable and sometimes the only option if your printer is new to market or uncommon. Remanufactured ink is a genuine brand cartridge that has gone through one cycle of use. After use, the cartridge is recycled, acquired by a remanufacturing facility and put through a rigorous professional refurbishing process. During the refurbishing process the cartridge is disassembled, thoroughly cleaned and tested for quality. It's then carefully refilled, tested again and brought back to life. Buying remanufactured prevents one less cartridge from ending up in a landfill. A compatible cartridge is a brand new ink cartridge built by a manufacturer other than your printer. It's like buying the generic version of the genuine brand. Most are uniquely designed to differentiate from genuine cartridges. Despite any structural difference you may notice, the cartridge will still fit in your machine and print a full yield, just like the original brand.
Price Factors Many printer manufacturers follow the razor-and-blades business model which may result in higher priced genuine cartridges. Remanufactured ink is much cheaper than the original brand ink. It's far more cost effective to refurbish a previously used cartridge than create a new OEM from scratch. Compatible ink is much cheaper than the original brand. Compatible suppliers don't have to worry about the additional costs that hinder OEMs like new printers or firmware, which lets them keep prices low.
Quality Original cartridges work extremely well and are covered under a warranty by the printer manufacturer High quality remanufactured ink will match the quality of the original, but not all remanufactured ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results. High quality compatible ink will match the quality of the original, but not all compatible ink is created equal. Make sure you buy from a reputable supplier in order to get the absolute best results.
What's the difference between ink and toner cartridges?
Ink Cartridges Toner Cartridges
Printer Type Work with inkjet printers Work with laser printers
Material Liquid ink Dry powder
How it works Inkjet printers use a series of nozzles that spray tiny drops of ink directly on the print suface Laser toner printers use static electricity and heat to bond dry toner powder to a page
Commonly used by Casual home users, small business and photographers Large businesses and schools
Number of Pages You Can Print A cartridge's page yield is the estimated number of pages you can print. Page yield is based on 5% page coverage. This means that the quoted page yield is based upon printed pages where only 5% of the page has been imprinted with ink. For example, a short memo has approximately 5% coverage. If you have a cartridge that has a yield of 500 pages, it can print 500 pages of that short memo. If you are printing letters, photos or graphics, your coverage will vary greatly and your page yield will drop significantly.
Cartridge Warranty and Shelf Life Most ink and toner cartridges include a warranty or "best by" date on their box. Remanufactured and compatible ink cartridges can last 12-18 months unopened, and toner cartridges can last up to 3 years.
Cartridge Care and Storage Only open a cartridge when you need it. Opened cartridges will eventually dry out, especially if the protective tape or clip has been removed. If you have an open ink cartridge around and would like to try and prevent it from drying out, place it nozzle side up in a plastic airtight tub. If your cartridge came with protective tape or a clip reapply both before storing. Place a damp cloth or paper towel in the tub, next to the cartridge and keep it stored in a cool, dark place.
