Rated 3 out of 5 by Customer81223 from pricey A good product that is certainly more reliable than recycled clones, but it annoys me when the consumables cost as much or more than the original equipment.

Rated 5 out of 5 by KYGal2019 from Great quality My 9 year old HP laser printer needed toner desperately! I'm so glad I replaced it, I used to dread printing because it would have a dark line down the center, it prints wonderful once again and I no longer dread printing! Oh yeah, shipping was free!!! Thanks HP! :-)

Rated 5 out of 5 by drew3611 from adjust with the flow It was great as usual. I was sorry that you were out of the tri-color multipack for my 1518ni color LaserJet. In these times of shortages, you might consider offering the same (collective) bargain price when someone orders the three individual cartridges. Just a thought. I ended up ordering elsewhere to get that product.

is this a refill or a new toner

Asked by: Judico
Thanks for your question! The HP 125A Black Original LaserJet Toner Cartridge is a new toner cartridge, not a refill.

I have a CP1215 and I am wanting to make sure that the black ink cartridge 125A that is compatible has iron oxide in it as this is needed for my printable decal to be able to be fired on to glass in my kiln project. Thanks for your help.

Asked by: Anonymous
Thank you for your interest in the 125A toner cartridge. That toner does not contain high amounts of iron-oxide like the toners MICR toners do. The exact compound that makes the styrene acrylate copolymer is not available which makes up the majority of the 125A toner. HP at this time does not make LaserJet printers or toners that have a higher concentration of iron-oxide. Troy Group is a partner of HP's that does make those specific HP units and MICR toner cartridges.
