⚖️ Expert Verdict
The HP M404dn is a fantastic small-business workhorse, but the HL-L6400DW is a flagship departmental machine. The Brother is significantly faster (52ppm vs 40ppm) and features a much larger standard paper capacity. While HP’s security suite is top-tier, the HL-L6400DW offers better expandability and even lower running costs for very high-volume users. For a busy workgroup that requires the absolute best in speed and paper handling, the HL-L6400DW is the clear winner for its superior departmental performance.
