Do these laser printers print double-sided automatically?

Most picks here include automatic duplex (two-sided) printing, including the Brother DCP-L2640DW, Canon MF287dw, MF465dw II, and LBP246dw II. The budget Brother HL-L2405W is a notable exception, multiple verified-purchase and r/printers reviewers flag that it prints one side only and requires manual flipping.
