HP C3167A LaserJet 5Si MX Printer 24ppm 600dpi Network LocalTalk 10Base-T BNC

The HP C3167A is the LaserJet 5Si MX, a high-speed workgroup laser printer built for demanding office and departmental environments. Introduced in the mid-1990s, it delivers 24 pages per minute at 600 dpi resolution and ships with built-in multi-protocol networking — making it one of the more capable printers of its generation. The "MX" designation indicates the fully-loaded network model with LocalTalk, 10Base-T Ethernet, and BNC (10Base-2) coax interfaces all installed from the factory.

Applications

The LaserJet 5Si MX was designed for high-volume departmental printing in corporate and institutional settings. Its built-in multi-protocol networking made it compatible with PC networks (via 10Base-T or BNC Ethernet) as well as Apple Macintosh environments (via LocalTalk/AppleTalk) — a significant advantage in the mixed-platform offices of the mid-1990s. These printers were commonly deployed in law firms, universities, engineering departments, and financial offices that needed fast, reliable monochrome output shared across a workgroup. The LaserJet 5Si series was HP's flagship departmental printer of the era, offering duty cycles and paper handling that exceeded typical desktop models of the time. Today, these printers still function well with modern operating systems that include legacy HP PCL drivers, and they remain in use in environments where high-capacity monochrome laser printing is needed and toner cost matters more than feature sets.
