HP C2951A parallel printer cable 9 ft DB25 to 36 pin Centronics

SKU CH-YCWD-TZ7YS MPN C2951A

Connects a PC to a parallel printer with an IEEE 1284-compliant, double-shielded 9 ft cable

  • Features• Parallel cable complies with IEEE 1284 specification • 9'
  • Compliant IEEE 1284 parallel connection for reliable printing
  • 9 ft length gives flexible device placement
  • DB25 to 36 pin Centronics fits legacy ports
  • Low-capacitance twisted pair reduces signal interference
  • Double-shielded impedance-matched construction protects data integrity

Purpose-built parallel link

The HP C2951A is a nine-foot cable that connects a DB25 parallel port to a 36-pin Centronics male connector. It targets users maintaining legacy printers, scanners or industrial equipment that still rely on the IEEE 1284 interface. The low-capacitance, impedance-matched construction preserves signal integrity over the full three-metre length.

Build integration

The double-shielded, twisted-pair design reduces crosstalk so the cable sits cleanly alongside power leads in tight enclosures. Its straight DB25 and Centronics ends need no adapters or gender changers, freeing rear-panel space on the host system. No active electronics are present, so the link draws no power and adds no driver overhead.

Capacity and headroom

Compliance with the 1284 specification means the cable supports the full parallel throughput the host controller provides. It handles standard byte-wide transfers and bidirectional modes without degradation. Runs longer than three metres or devices requiring higher signalling rates will exceed the cable’s rated performance envelope.

Questions about this item

What is the maximum cable length before signal integrity drops under sustained printing?

The cable is 9 ft long and built to the IEEE 1284 specification with twisted-pair, double-shielded construction for reliable data transfer at that distance.

Does the cable generate noticeable heat or draw extra power during all-day printing?

As a passive parallel cable it draws no external power and produces no measurable heat during continuous operation.

Which ports must my computer and printer already have for this cable to connect?

Your computer needs a DB25 parallel port and your printer needs a 36-pin Centronics male port for the cable to fit.
