The CH351Q acts as a bridge between the PCI bus and the IEEE 1284 parallel port interface.
Many MS-DOS based or older Windows XP programs look exclusively for the physical address 0x378 . ch351q parallel port driver
The CH351Q parallel port driver is designed to work with various operating systems, including Windows, Linux, and macOS. It provides a set of instructions that allow the operating system to send and receive data to and from devices connected to the parallel port.
This is a unified driver installation package and EEPROM configuration tool designed to support a wide array of PCI multi-I/O cards from WCH. The driver is notable for several reasons:
Here are its key technical specifications:

CH351Q is a single, specific chip model. However, the chip can be configured via its firmware to operate in different modes (e.g., dual-serial or single-parallel). The datasheet may refer to different configuration variants as CH351Q_S , CH351Q_P , or CH351Q_X .
The CH351Q parallel port driver is a software component designed to enable communication between a computer and devices connected to a parallel port, utilizing the CH351Q chip. This driver is particularly useful for older systems or specific industrial and technical applications where parallel port connectivity is still required. Here's an overview of its performance and functionality:
The CH351Q typically operates at 3.3V, with 5V-tolerant I/O pins, making it suitable for interfacing with older parallel devices that expect 5V logic levels.
Capable of bi-directional data transmission at speeds up to 2.0 MB/s .
