Edgeport/21 parallel port not appearing

My Edgeport/21 functions perfectly on an older XP Home machine, but not on a newer XP Media Center HP 1547c. Using the latest drivers, the serial ports install, but Device Manager does not show the parallel port. I have a second /21 and a /421 that replicate the problem. Any idea what’s going on with the HP?


Do you see anything in your device manager with a yellow exclamation mark? If so, is it related to our product/USB?

It’s also possible that the port is there but you’re not recognizing it correctly. The PP does not install as a traditional LPTx. It will install as “Usb printing support” in the Universal Serial Bus Controller category.

Would you please check that and let me know what you find?

It was indeed the latter, and I had been looking for LPTx. It installed on USB001, “Virtual printer port for USB.” Not having seen any LPTx under “Ports” in Device Manager, I hadn’t scrolled down to discover that choice when attempting the printer install. I had seen “USB printing support” earlier, but didn’t relate that to the Edgeport. Thanks, Mike!



My pleasure, I apologize that it’s not more clear.

Take care,
