I've been printing fine from AutoCAD all day, just went to print and when I changed it to previous plot I get a warning that Epson MFC-944CN: This plotter configuration cannot be used for one of these reasons: the drive cannot be found, the device cannot be found, or the driver has a problem.  The None plot device has been substituted.I printed a test page page and from two other windows applications no problem, restarted AutoCAD, restarted my PC, still no good and now the printer isn't even showing up in the plot options for AutoCAD?

I got it, somehow under options>plot and publish, hide system printers was checked?
