Ease of Use:


  • Cost effective product
    Verified BuyerReviewed by Awake5 - November 30, 2013

    One of the smartest moves I ever made was to get rid of an HP printer that required five expensive cartridges - 2 black, and 3 color. If one ran out, all 5 cartridges had to be replaced. I had worked extensively with Brother printers at my job and found them to always be reliable and the accessories to be very affordable. These cartridges (there are two, one high volume for lots of printing and this one) are sold at a good price and last a long time. I have found no need for a color printer and have been very pleased with Brother products including this toner. There is return postage included so you can recycle the empty cartridge at no cost. Good products, good deal!

    Ease of Use:

  • Does almost everything for a modest price
    Verified BuyerReviewed by PearlShopper2 - June 25, 2014

    Incredibly fast, a teacher can print a high quality class set of worksheets in one minute, or two sided automatically within 3 minutes. Pages emerge face down in their original order. Wireless, can be anywhere in the house and moved at any time. Two sided automatically instantly, no drying time wasted like ink jet. Load half a ream at a time, or a single sheet of specialty paper. Make perfect copies without a computer in seconds. Scan to computer or PDF. Sorry, no FAX, no document feeder, scans and copies one side at a time, no email address, you must be on the network, really long, long installation process requiring a reboot like last century, but low price makes up for these.

  • Best printer I have ever owned
    Verified BuyerReviewed by socratezzz - April 22, 2015

    About 80% of the time, I need a printer to print a few pages. Perhaps a travel itinerary, a boarding pass, a receipt, etc. Using an inkjet color printer is a costly way to meet your everyday printing needs. I have a color Inkjet, but thanks to this Brothers B&W laser printer, I can print and print and print what I need without worrying if I am running out of ink. And the cartridge ready to replace when it eventually runs out of ink. It is the smartest buy i have done. Don't rely on your color printer to do your daily printing needs, and free yourself of if the Cyan, or other color ink cartridges are low. Invest in a B&W printer like Brothers and just keep a extra cartridge in hand and you are all set.
