Go to Amazon and get a 'parallel to USB' printer cable.
This is the first one in the search results that is also from a brand I've actually heard of. unfortuantely it is out of stock, but it will get you on the right path: https://www.amazon.com/Sabrent-SBT-UPPC-Centronics-Printer-Cable/dp/B0007UVRVO
https://www.amazon.com/Sabrent-SBT-UPPC-Centronics-Printer-Cable/dp/B0007UVRVO
That should do the trick. Specifically, the cable you seek is a Centronics cable.
