Donald:
I keep all 4 pen widths (.25, .35, .5 & .7 mm) in a variety of colors for
both bond and mylar available. I order the HP pens and use the adapter
(available from Ioline or most of the pen makers) to get the fit. Make
sure to order new adapters – they wear out after a year or two and
fine-tune adjustments become a headache. Stick with the ink pens… the
fiber-tips don't work well with this plotter. The bond pens dry almost
immediately, and the bond media via roll is handy to work with.
Feel free to fire away with the questions… I can always defer to Evan!
