Would this work? It appears to be what I've got I think:
https://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USBIt has the FW ports but also USB 3 which I "think" I have although I don't have a cord like that nor do I have a port like that. My USB ports of which there are only 2 so I can't spare one full time look like the standard USB I'm used to, bigger, wider.

Believe the Printer is indeed running on USB 3... the part that plugs in the printer resembles that little USB connection. Surprises me though... if you want to talk ancient, it's that printer... maybe 12 to 14 years old and still works like a top. Until lately I've still gotten updates for it. To get a new one though is coming... after the external HD.
