Brother DCP-7045N black-and-white laser printer with sheet-fed document scanner and flatbed scanner.
Ethernet and USB connections. No Wi-Fi. Works happily with the latest version of macOS and should be fine with Windows.
This is an old machine and it's a bit of a beast, but it's in good condition and full working order. The toner cartridge is half full, so should be good for 1000 pages at least, and it had a new drum not long ago. The print is not as dark as it might be, but it's perfectly useable. New toner is quite inexpensive compared to an inkjet printer.
The flatbed scanner is nothing wonderful but it's OK. The sheet-fed scanner is awesome for digitising piles of documents.
