Im super new to all of this and recently purchased a plotter and im self learning illustrator. I cant see to see my plotter as a printer option to cut my desins. Please can someone help?
You will have to find and install a printer driver specific to your new plotter. It should be available for download from the plotter manufacturer's website.
Unfortunately some vinyl cutting software don't support direct plotter cutting from Illustrator. I would contact Sign Master and ask if they have a plug-in.
Other option: export your esign in a format that Signmaster software can read and then plot.
