Had a new plotter configuration installed to an existing plotter to get some accounting software to work correctly. But now I can't get our custom paper sizes to import to this new plotter. I attached a pmp that has all our custom paper sizes, it attaches but doesn't take. I tried to add the custom paper sizes individually but the pc3 won't let me add any. All our other plotters configs work fine but this one doesn't allow me to customize anything.
