PCIe Combo Serial Parallel Expansion Card PCI Express to Printer LPT Port RS232 Com Port Adapter IEEE 1284 Controller Card WCH382 Chip for Desktop PC Windows 10 with Low Bracket

Bottom line: The PCIe Combo Serial Parallel Expansion Card PCI Express to Printer LPT ($21.98 on Amazon as of 2026-10-06): Adds both RS232 serial and IEEE 1284 parallel LPT ports on one x1 PCIe slot; main trade-off: drivers ship on a CD (CH38XDRV folder) which many modern builds cannot read.

Pros & Cons

Pros

  • ✓ Adds both RS232 serial and IEEE 1284 parallel LPT ports on one x1 PCIe slot
  • ✓ WCH382 chip supports SPP, PS2, EPP and ECP parallel modes for legacy peripherals
  • ✓ Parallel port data rates up to 1.5Mbps for older printers and dongles
  • ✓ Serial side runs 50bps to 16Mbps and supports RS232, RS485 and RS422 modes
  • ✓ Low-profile bracket included, plus driver coverage from Windows 2000 through 11 and Linux

Cons

  • ✗ Drivers ship on a CD (CH38XDRV folder) which many modern builds cannot read
  • ✗ Listing cites ExpressCard/34mm compliance, confusing for a desktop PCIe card
  • ✗ Only one serial and one parallel port, so multi-device legacy setups need a second card
  • ✗ Support is contact-the-seller by message rather than a documented driver download page
