Green PCI expansion card with silver DB25 parallel port bracket

SMUGDESK

SMUGDESK PCI to DB25 LPT Parallel Port Card MCS9865 Chip

SKU CH-D6EQ-ETX26

Adds a DB25 parallel port via PCI slot using MCS9865 chip for legacy printers

  • Adds a DB25 LPT parallel port via a single PCI slot
  • MCS9865 chip ensures stable data transmission for legacy printing
  • IEEE1284 protocol compliant for broad 25Pin printer compatibility
  • Standard PCI bracket fits traditional desktop chassis and all PCI slots
  • Full driver support for Windows and Linux simplifies setup

Legacy Parallel Port Expansion

This PCI expansion card adds a single DB25 LPT parallel port to a desktop computer. It uses the MCS9865 controller chip to provide a stable connection for older parallel printers and industrial equipment. The card fits any standard PCI slot and includes drivers for Windows and Linux systems.

Users With PCI Slots and Parallel Devices

The card suits anyone who needs to connect a 25-pin parallel printer or peripheral to a motherboard that lacks a built-in LPT header. It complies with the IEEE1284 protocol for broad compatibility with legacy hardware. Builders whose systems only offer PCI Express slots cannot use this card.

MCS9865 Chip and IEEE1284 Compliance

The onboard MCS9865 chip manages data transmission to ensure reliable printing performance. Support for the IEEE1284 parallel protocol allows the adapter to work with most standard 25-pin parallel equipment. Verify that your motherboard has an available PCI slot before purchase.

Questions about this item

Should I choose this card for a single legacy parallel printer connection?

Yes, the card adds one DB25 LPT port using the MCS9865 chip, giving you exactly one parallel interface for a 25-pin printer or industrial device.

What does IEEE 1284 compliance mean for everyday printing?

It means the card follows the standard parallel protocol so data flows reliably to most 25-pin parallel printers without extra configuration.

How does the PCI interface affect the maximum throughput I will see?

The card plugs into a standard PCI slot, so the bus bandwidth and the IEEE 1284 implementation together set the practical speed ceiling for your parallel device.
