PCIe Combo Serial Parallel Expansion Card PCI Express to Printer LPT Port RS232 Com Port Adapter IEEE 1284 Controller Card WCH382 Chip for Desktop PC with Low Bracket

A customer had his old computer died. It ran a laser engraver and a very old diamond engraver, both connected with a LPT Port only. I built him a new computer, but new motherboards don't have LPT ports, I I gave this a try. This was able to communicate with both using a splitter, customer is happy, so am I.

I was not sure if this adaptor would work before I order it. But the price is cheap, and I need to set up my backup PC for my business. Why not try? Both parallel and serial ports are working like charm. My business use a very old management software, 20 years old. And it checks a Marx security dongle through the parallel port. I only runs on Windows XP. Also it uses RS-232C serial port to connect the entire 15 pieces of equipment in my business. It all works nicely. Driver installation was just a couple minutes thanks to other customers tip, use CH38XDRV. Without their advice, I would've spent a lot more time. I only hope the board won't break at least for a couple years.

Fitted well made fitting the card easy in a small form factor pc

This works in Windows 10 and I'm going to assume it'll work in Windows 11 as well. Just know that drivers for this are going to be tough to come across so invest in the Snappy Driver Installer Origin program. It found the driver for this right away and works perfectly.

Not a lot of documentation provided. Tried a couple of drivers on the CD and finally got it working with one of the WCH drivers. There’s two can’t remember which one I eventually used. Spent a morning trying all that out. It’s only a single serial and parallel board but two serial and two parallel have appeared on device manager. It works with my parallel port dongle which was my only requirement.
