It may be Samsung's own ML-1915 that is the biggest competitor to the ML-2580N. OK, this machine has Ethernet built-in and a faster print speed, at least on paper. Under test the difference in speed is no more than a couple of pages per minute, though, and the difference in price is over £20.
For some reason best known to itself, Samsung has also decided not to include the page print button of the cheaper machine, choosing instead to provide a function that is of no use to the customer, only to the salesperson.
If you want to share a mono laser printer between a couple of people, you may feel the advantage of having Ethernet built in is worth the extra money, but remember you can still share a machine with a USB connection via any Windows PC. Print quality and speeds are good and in other respects this printer is excellent value.
