3 years old working fine. Cartridges in, not dried out, alternate Brand new cartridges included too

"The Brother DCP-L3550CDW is a wireless all-in-one color LED printer tailored for home offices and small business environments. It functions as a 3-in-1 machine that handles printing, copying, and scanning.
Regarding printing technology, it utilizes LED technology, which provides a fast and reliable alternative to traditional laser printing. It delivers print speeds of up to 18 pages per minute for both monochrome and color documents. It automatically prints double-sided documents to reduce paper consumption. For document handling, it features a 250-sheet lower paper tray and a 50-sheet Automatic Document Feeder for hands-free scanning and copying of multi-page documents. It connects via Wi-Fi, Ethernet, and USB, alongside compatibility for mobile printing apps like Apple AirPrint and Mopria. The machine is controlled using a 9.3 cm color touchscreen interface.
Common user and expert feedback highlights low noise output, as users highly praise its quiet operation under 47 decibels. Another advantage is toner longevity, since dry toner cartridges do not dry out over periods of inactivity. On the downside, users note its large size and weight, measuring roughly 41 cm wide and deep, and weighing over 23 kg, which demands a dedicated desk. Expert testing also notes that while it produces sharp business graphics, it is not intended for high-quality, professional glossy photo printing.
