Designjet T120 / T520

My Windows7 32bit computer keeps having video "events", actually resets, which is apparently a known bug in Windows 7. I have another computer running Win7 64 bit, however, I'm looking at possible upgrading my Designjet 430 to a T120 or possibly T520. I've tried connecting Win 10 to the 430 through a network and it DOES print the test page, but I haven't tried with Terramodel yet. I have an OLD version of AutoCAD LT 2000 which I don't use to print.

I'm a relatively low volume user so I'm probably looking at the T120 for price. Terramodel can use windows plotters so I think I'm OK there.

Reports and/or reviews of the T-120 would be appreciated.
