The Spooler allows you to simultaneously manage multiple cutting jobs with multiple cutters. This gives you the possibility to select which cutter you wish to send your work to and define specific settings for the specific work. It is only included with the Premium version of Pro 2 which is the version that the free trial runs in. It needs to be installed during the installation of Pro 2. (There is a check box during the installation you mark to install the spooler) If you did not install the spooler during the initial installation, please download and reinstall Pro 2 from our website here but check the option to install the spooler this time.
Once installed, you can set up the cutter models in the spooler then be able to choose the spooler as the output device in the cutter setup for Pro 2.
Learn more about how to set up the spooler on either MAC or Windows computers in the linked articles.
