Wch Ch350l Parallel Port Driver -

For Linux users (Ubuntu, Debian, Raspberry Pi OS with PCIe), the driver is built-in.

Use the Official CH35XDRV.EXE package. This installer typically handles the configuration of the EEPROM and registers the LPT port in the Device Manager. Wch Ch350l Parallel Port Driver

The CH350L chip is part of WCH's broader family of interface controllers. It is primarily used in PCI Express expansion cards to provide a standard IEEE 1284 parallel interface. For Linux users (Ubuntu, Debian, Raspberry Pi OS

The CH350L driver is frequently sought for scenarios where modern technology fails to interface with older, mission-critical hardware: The CH350L chip is part of WCH's broader

The CH350L chip functions as a bridge between the and an IEEE 1284-compliant parallel interface. Unlike USB-to-Parallel adapters, which often struggle with non-printer devices like hardware dongles or CNC controllers, the CH350L driver creates a "true" physical port in the operating system.

Many older CNC machines rely on precise timing through an LPT port. The CH350L’s ability to be configured in DOS or Linux for specific I/O port addresses (e.g., 0x378) is vital for software like LinuxCNC .

The solves two problems:
