    Reviewed in the United States on May 22, 2019
    Verified Purchase
    Ordering this product is the right thing to do if you have an older HP Laser Printer. I have the HP LaserJet 4250, and the toner did just what it was supposed to do. You can't go wrong with HP printers. They are the industry standard.

    Imperative that you use an HP authentic product with the laser printer. You can kid yourself all you want by using the knock-offs. You won't have the quality and you could be causing problems to your printer.

    1.0 out of 5 stars Not "Original" HP OEM toner cartridge
    Reviewed in the United States on March 27, 2014
    Verified Purchase
    I thought I was buying an original HP OEM cartridge as per the picture. I received a third party (MSE brand) cartridge instead from Qualtiy Printers. After pulling the tape and inserting the toner cartridge I received a printer error saying the tape needed to be removed. After a few tries, I could not get the printer to work with this toner as it kept saying that the tape needed to be removed although it already had been removed. Advertising the cartridge as an "HP 42A Original" is deceptive. Unfortunately I have to return it.
