HP’s ePrint technology lets you receive and print documents anytime, anywhere from any mobile device by assigning your MFP (or printer) an email address. To print, simply send an email containing your document to your MFP’s (or printer’s) address.1 Faster performance — HP’s LaserJet Pro M1536dnf MFP boasts a faster print/copy speed, faster first-page-out times from ready and energy-saving modes, and a slightly faster first-copy-out time than the Brother MFC-7840W.2 More energy efficient — The advanced, fast-heating ceramic element within HP’s Instant-on Fuser consumes far HP LaserJet Pro M1536dnf MFP less energy than the conventional fuser employed by the Brother units.3 Up to 26 ppm Better paper handling — HP delivers autoduplexing standard, while it’s not even optional with the Brother MFC-7840W.4 And HP’s standard tray accepts up to 43-lb. bond, but Brother’s standard tray only accepts up to 28-lb. bond — an especially big deal when you consider Brother’s manual trays only support 1 sheet at a time.3 Virtually maintenance free — HP LaserJet Pro M1536dnf MFP print cartridges integrate the toner, drum, primary charge roller, and developer into a single, easy-to-replace, mess-free unit. Brother’s complex 2-piece system forces you to stock and replace an extra consumable and creates extra maintenance — every time MFC-7840W users replace toner they must clean the corona wire to prevent damage that can lead to print-quality defects.

Brother MFC-7840W Brother’s 2-piece system also can compromise print quality, since its imaging drum only gets replaced every Up to 23 ppm 12,000 pages instead of being replaced every time you change out toner like with HP.
