Printer won't connect to Cura

[holotav 0]

Hi everyone,

A warning in advance--I'm basically a beginner with 3D printers, so I won't understand a lot of jargon.

I'm working at a museum and we've had a 3D printer since December 2015. It was an Ultimaker 2 Extended that we upgraded to an Extended+ last year. We haven't used the printer with Cura for at least 8 months. Additionally, the computer we had been using Cura on recently became unusable and has been scrapped.

I installed the latest edition of Cura (2.6.2) on a spare computer that runs Windows 8. Unfortunately, when I plug in the printer to the computer to see if there are any firmware updates, the Cura software indicates that there is no printer connected. The computer itself does indicate that the usb has been connected, so it's not the cable as far as I can tell.

I tried installing Cura 2.5.0 and 15.04.6 as well to see if a different version would work, but no dice.

Any suggestions? Let me know if there's more information needed.

Thanks!
