Using roland GX-24 to write?

[Country Signs 0]

I Have a Roland GX-24 and i have a request to make paint masks for airplanes. He asked if my cutter would write out the design on paper so he can get an idea of how it will fit on the plane before i cut it out on vinyl.  Just wondering if there is a pen of some kind out there to put in the cutter instead of the blade and if so what the pressure settings might be?

zero offset.  You will have to work with the pressure.
