Subject: Need Rohs 721 Cutting Plotter Driver for PC

Message: Hello,

I am looking for the correct PC driver for a Rohs 721 cutting plotter. My operating system is [Windows 10 / Windows 11 / etc.].

The plotter connects via USB. I have tried using generic HP-GL drivers, but I want to ensure optimal performance. Does anyone have a link to the official driver, or know which compatible driver (e.g., Roland or Generic Text Only) works best with the Rohs 721?

Also, do I need a specific USB-to-serial chip driver (CH340/PL2303) for this model?

Thank you.
