The CH382L is a high-performance PCI-Express to dual-serial and parallel port controller. It is frequently found on budget-friendly expansion cards used to connect older printers, scanners, or industrial equipment to modern computers. Because modern operating systems like Windows 10 and 11 do not always include these specific drivers in their default library, manual installation is usually required to make the "LPT" port visible in the Device Manager. Where to Find the Driver
If you had a previous serial or parallel port card, uninstall the old drivers before installing the WCH CH382L driver. Wrong parallel mode (EPP/ECP vs SPP)
: Achieves parallel transfer speeds up to 1.5 Mbps.
Modern versions of Windows enforce strict driver signature verification. If Windows blocks the driver installation:
: Search for "CH382" in the WCH downloads section to access the combined serial/parallel port driver executable. 2. Supported Operating Systems
