HP 81A Black Toner Cartridge | Works with HP LaserJet Enterprise M604, M605, M606 Series; HP LaserJet Enterprise MFP M630 Series | CF281A

Toner works as advertised. We use original HP products for our main printer as we yield more than stated and the quality is perfect. We are an accounting firm, so you can see that the coverage is pretty good too. In order to save money on our individual printers we usually don't get Manufacturers toner as there are many companies out there that sell compatible toner for a fraction of the price, but for our main printer it is not worth the risk. Keep in mind that for non-manufacture printers, we spend less than $300 for the printers which means that if we have a problem, the overall cost is still much lower per printer per year. I will never purchase a compatible toner for our main printer

This is a high-yield version of the standard version of this toner cartridge. It IS expensive, but when you consider how long it lasts, it's a bargain. My printer is an Enterprise-class HP M605 Laserjet and it gets A LOT of heavy use. The last time I replaced the toner cartridge was about 5-6 years and 8-10 boxes x5,000 sheets per box ago. I bought this latest cartridge a couple weeks after I got a 'Replace Cartridge' message the printer sent and received it a few days later, and three weeks later the print is still showing no sign that it really is time to replace the cartridge.

We were happy to find these HP print cartridges on AMAZON because a local vendor is charging double the price. Long Live Amazon!

liked the ink from HP but the 81x high yield did not fit my new HP M604 printer and found out it only uses an 81A only and ended up throwing away the 81x. I wish HP had warned me about not being able to use the 81x in my printer. I will only get the 81A from now on and be aware that some of the M604 will not support the 81x.

Product functions as described. Satisfied with the product

I have purchased this item several times from Amazon. It comes quickly and works beautifully.

I purchased this HP Toner in October for a printer we have at the office, and I have to say that I'm impressed, because it's still going strong. The cartridge was very easy to install, and the print quality is still very clear.

This HP 81x is the best quality for our office and we go thru one ever quarter. We get app 24,000 per cartridge! We have purchased this 81x 6 times. We are not using any knock off in our office.

Works perfect. Thank you

El tóner no sirve para la impresora que se publicita en la página web. No he reclamado porque ya lo había abierto para insertarlo en la máquina. el tipo de toner es el mismo que usa la impresora para el que lo he comprado, pero al ser un tamaño de "gran capacidad" al insertarlo en la impresora no cabe. He tenido que tirarlo al reciclaje y comprar otro tóner en una empresa de la competencia. Saludos.

Alles Prima!
