I plot using an old laptop running XP on our network as a server. I thought maybe the Arial Rounded MT Bold should be on the laptop, so I installed that font. I plotted a Word document from the laptop to the 450c and the font was properly plotted. So . . .
The problem is not a missing font on my plot server.
The problem is not XP.
The problem is not the old laptop.
The problem is not that the plotter won't plot Arial Rounded MT Bold.
Some of the text is underlined and the underline plots, but not the font. I didn't mess around with settings, I just changed the font from Arial and Arial narrow (both of which plot) to Arial Rounded MT Bold and poof, no text in the plot.
I went to the user forums @ Microsoft, but haven't heard anything.
I am attaching a file if anyone wants to see if they can figure it out.
