• Verify downloaded files with provided checksums/signatures if available.
• Scan files with antivirus before installing.

Frequently Asked Questions (FAQ)

6. Important Note on Legacy Software

Many older DOS or Windows 9x applications require direct I/O access to 0x378, 0x278, or 0x3BC. The CH382L does not use standard ISA I/O addresses — it uses PCIe memory-mapped I/O.

To use legacy software:

• Use a port redirector like UserPort or GiveIO (Windows 10/11 may block these for security).
• Or use a virtual machine (VMware/VirtualBox) with PCIe passthrough if your hardware supports it.

✅ Vendor-Specific (Card Manufacturers)

If you bought a card from Startech, Delock, or Sunix, use their provided driver package — but it will still be based on WCH’s reference driver.

4. Installation Instructions

Conclusion

The WCH CH382L remains a reliable bridge between modern PCIe motherboards and legacy parallel peripherals. While the driver download and installation process can seem daunting, following the official steps above will get your parallel port up and running. Whether you're resurrecting a vintage printer or powering a homemade CNC router, the CH382L – with its proper driver – is the key.
