Wch Ch350l Parallel Port - Driver

1. Overview The WCH CH350L is a PCIe (PCI Express) to LPT (Parallel Port) controller chip manufactured by Nanjing Qinheng Microelectronics (WCH). Unlike legacy native parallel ports, this chip allows modern motherboards without a Southbridge LPT header to gain a fully functional IEEE 1284-compliant parallel port via a PCI Express slot.
