NONE DoubleDiamond™ Warranty (Standard)

Product Features

  • Compatible with all popular software, including graphics and Windows® programs.
  • Throughput of up to 75,000 characters per second.
  • Supports up to four PCs.


  • Unique Interface Matching Technology produces a significant advantage over direct connection and improves printing performance.
  • Ideal for Windows and graphics-intensive applications.

  • With today's high-performance software applications, users demand more memory, larger hard disks, faster processors, and more powerful laser printers. Improve the printing performance of your PCs and printers simply by connecting them to a more intelligent switch.

    The BLACK BOX® Intelligent Printer Switch features a unique Interface Matching Technology that produces a significant advantage over direct connection. Just watch what happens to your printing performance!

    This simple switch is a fast, automatic data switch that enables you to easily share a printer between four computers.

    The Intelligent Printer Switch is versatile, too. It works with all computers, plotters, and printers that have standard Centronics® parallel interfaces. It's compatible with all versions of Windows®. And the switch has test, auto form feed, and time-out features.

    This switch works on a first-come, first-served basis. The first computer to send data is connected to the printer through the switch. Other computers sending print jobs are queued and receive a printer busy signal. Once the first computer is finished printing, the next computer is automatically connected to the printer.
