T642N
The Lexmark T642N brought networked mono printing to mid-size workgroups that needed more speed than a T640 could offer. Ethernet connectivity made sharing effortless, turning one printer into a department resource. Lexmark's sturdy paper path handled the extra volume without complaint. The 640H cartridge kept per-page costs predictable, and compatible 640H toner is the smart refill choice for T642N units still pulling daily duty.
