HP 45 (51645A) Black Original Ink Cartridge is rated 4.63 out of 5 by 59.
Rated 5 out of 5 by from Ink Cartridge for an HP war horse I'm still using the first printer (HP Deskjet 722C) I purchased. It's a war horse that has assisted with years of teaching, union negotiations, Statewide committee work, and volumes of files. When the local stores stopped stocking the in cartridges I stocked up on as many as I could find. Then the last one went dry. I didn't want to have to purchase a new printer. Fortunately, I discovered that HP still stocked ink cartridges. Within two days I was back in business. OK, my printer's not an AIO, and I have to hold onto an older computer to operate it, but it does an excellent job. Only thing better would be an updated driver for my new computer.

Rated 5 out of 5 by from I'm certainly glad to find these cartridges! My printer is admittedly a relic of the previous century but it does things that newer one don't; unless one acquires a multi-task box the size of a small car.

Rated 5 out of 5 by 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 from Printer 932 still great. Have 2 932'. Black great! I use black ink only. Prints beautifully and fast on DRAFT. Never use color. The printer does not use color at all when printing black (greyscale). This is unlike all 4 cartridge HP printers which use or need the 3 color cartridges operating even when printing in black only!

Rated 5 out of 5 by 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 from Long Lasting! I just bought the real HP ink after using the generic brands. Actually, my HP printer would no longer work with the cheap ink. Wondering if this is a feature of all HP printers? However, I'm glad I switched back and have no more "out of ink" problems.

Rated 5 out of 5 by from Trustworthy backup After having to use my G55 Officejet backup printer (which hadn't been in use for around 5 years), I was surprised to find that the 45 Black cartridge still had life in it and that it hadn't dried/clogged up from sitting idle. The 78 Color had already been depleted. Thankful that HP still sold the 45 and 78 cartridges. Purchased the 78XL Tri-Color for the first time. For general all purpose printing (including photos), I love these cartridges in lieu of the new 4-cartridge system.

Rated 5 out of 5 by from Quality product All my printers have been HP's. They are a quality product. Being a retired senior citizen, I just wish the cartridges were more affordable. I purchased directly from HP this time since the last (2) that I purchased (cheaper) from Amazon were already 3 years old and they only lasted 4 months. Any way I can save on purchases?

Rated 5 out of 5 by 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!

Rated 5 out of 5 by 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 5 out of 5 by from I'll never re-load cartridges again! I thought I'd save money by using a coupon to the big box store to get my old deskjet cartridges re-filled. Three months later, neither of the two refills were working, and I was frustrated over their poor quality and the loss of my money. HP service was extremely quick, and my work looks professional again. Thank you.
