Rated 5 out of 5 by Betty47 from HP has made the 820C ink jet printer so good, it just helps on printing out in excellence. My problem has been finding 45 ink. Since I found I could order my ink from HP, my day has been saved! The ink is absolutely great for which I’m very thankful for. Thank you HP for the excellent products you make and sell.

Rated 2 out of 5 by over 60 in kc from It works some of the time Bought 2. Have to remove the cartridge and shake it to make it work after the weekend with no use. Have to shake it until the ink comes out then it will work again. Printer is for business use.

Rated 5 out of 5 by Barb108 from Yay! I lucked out! I have had a hard time finding HP45 computer cartridges; I just find them sporadically, and it's been awfully frustrating. Then I got the idea of looking you up on line and lucked out. I now have my HP45, ordered with the help of a very helpful salesperson, and you can be sure I'll call again when I need another one. Thank you a thousand times over! Barbara H. Vinson

Rated 5 out of 5 by Ter192 from I do trust your product. I have used ink replacement cartridges and they seem to always leak. The last one I bought (I do not do this often) it leaked nearly all the ink into my HP printer. I will from now on use cartridges only from HP.

Rated 5 out of 5 by wbg10 from Keeping My HP6127 DeskJet Going Thank you for continuing to offer the HP45 (and HP78/78XL) cartridges that allow me to keep my trusty DeskJet going. This little printer has been my workhorse for years and has proven more reliable for me than any of the newer printers I've purchased over the years. These ink cartridges work great and perform well. I keep several on hand at all times and order replacements several times a year. Great product.

Rated 2 out of 5 by HPGeezer from I put a new black cartridge into HP DeskJet 880C The new cartridge in the old printer did not print. The DeskJet 880C was an incredibly fine product. HP will no longer give support to the printer. Probably the cartridge was fine. What's needed is a new printer.

Rated 5 out of 5 by bro41 from HP Products Beat All I have been a purchaser of HP products for many years and have never been disappointed. The HP 45 ink cartridge, along with the HP 78 ink cartridge, have supported my HP K80xi printer for many years now. Because my local source for those cartridges no longer carried them, I tried their refill service. The resultant performance from these refill cartridges were less than satisfactory, so I began purchasing the 45 and 78 cartridges direct from HP. Thank you HP for your quality merchandise!

I have HP Officejet Pro 8600 Plus printer. I usually use ink cartridge # 951. Stores in my area do not have them. Are there other cartridge # I can use? Can I use 950? I need black ink NOW. If you have any compatible ones, I would like to order. Patra.

Asked by: Patra
Thank you for your question, the HP Office Jet Pro 8600 plus only uses HP 950 for black and HP 951 for color.

45 Black is great! My question is about 78 color cartridge - Why would HP only have the Black 45 and not the Color 78 to go along with it? The only HP printer to work perfectly every time is our DeskJet 990Cse printer after all these years!!
