I have been using the Brother Embroidery Software in my small embroidery business for about 20 years. It works on a parallel port key. As you know, most computers today do not have parallel ports. They now use USB. How can I convert this key to USB?
If you use the software with an embroidery machine that connects to your computer via a parallel port key, you can try a simple parallel port key to USB adapter on new computers. You can find this kind of cables on local shops, eBay, Amazon or others similar websites. Also, since you're using a new computer, you might need to update the software to the latest version.
