There are a LOT of counterfeit prolific chips out there that are just junk!
Using a laptop you don't have much choice (to bad it wasn't a desktop with serial/par pci card installed)
I wrote software for your Camm2. Search youtube for Tux Plot.
I use three camm2 engravers including a 2200.

I wrote an application to control this and many other devices, for Ubuntu , Mint, Debian Linux.
I have five roland engravers and plotters for testing Tux Plot so it runs them extra nice.

Check out "Tux Plot" on Youtube.
