We have two programs we use that require software keys to function. They are dongles that plug into the 25 pin female parallel port on the computer, and the printer cable itself plugs into them. Our laptop computers were just upgraded, but have only USB ports. I was hoping to use this cable: http://usbgear.com/USBG-LPT25.html for the dongles but was told by a tech guy it wouldn't work and "...there is no way to convert a software key to any USB device. You will need to add real hardware LPT ports". So fellow geeks - how do I get these keys to work with our new laptops? I have not purchased one of those cables - at $40 each it is an expensive "maybe this will work anyway" test.
