We use Onyx PosterShop to run 4 printers and we want to add a plotter to Onyx. (We use the Mimaki FineCut Illustrator plug-in to run our current Mimaki plotter and you can't add a second plotter to this software). So, we installed another Mimaki plotter in Onyx PosterShop yesterday. After downloading the correct drivers, everything seems to be working as it should. Onyx is communicating with the plotter. There are no errors or other problems indicated. When you click "cut job", a bar appears briefly on the screen indicating that the job has been sent, but the plotter doesn't start. HERE IS THE STRANGE PART - when you configure the plotter the first option is "Port Settings". The default is "Cut to File", but the dropbox shows a few other options, including USB, TCP/IP, etc. When you try to change it to USB, because that is how this plotter is connected, it won't let you. You hover over that option and it goes right back to "Cut to File". This seems like the culprit but I don't know how to fix it. In Device manager, the plotter shows up as a plotter and appears normal and connected. I'm stumped. Any suggestions? Thanks in advance!
