Ch3510 Parallel Port Driver ((top)) Here

The driver identifies the I/O address range assigned by the PCI bus (e.g.,

The CH3510 chip provides a hardware-level solution for adding parallel connectivity. Unlike USB-to-parallel adapters—which often struggle with timing-sensitive tasks—the CH3510 sits directly on the PCI bus, allowing for low-latency communication. : WCH CH351Q / CH351S / CH3510.

Furthermore, because modern CPUs are exponentially faster than the devices the CH3510 connects to, the driver often has to implement timing delays ch3510 parallel port driver

After reboot, open → Ports (COM & LPT) . You should see "PCIe Parallel Port (CH3510)" or similar. Right-click → Properties → Resources . Note the I/O range. It will likely be something like DC00 - DC07 – not the legacy 0378 .

A: Yes. The CH35X family driver is unified. One driver supports CH3510, CH3520 (dual port), CH3530 (parallel + serial), and CH3560. The driver identifies the I/O address range assigned

IRQ conflict or resource assignment failure. Fix:

The safest and most reliable driver is from the manufacturer: Note the I/O range

: Capable of speeds up to 1.5 Mbytes/sec , which is significantly faster than standard on-board parallel ports found in older machines.
