You can search for media profiles for your Roland printer from the Roland Profile Center website. If you don't have an account on Roland's website, you'll have to create a new user account.
You can then choose either "Roland" and "RolandPrintStudio", or select "Caldera" and any CalderaRIP version (media patches are not version specific, so even if it shows a Roland or CalderaRIP version other than what you are using, the media patch should still import and work fine on your version), to download media profiles from Roland:
Finally, install the downloaded profile media patch in the EasyMedia module.
Good to know
Some profiles can also be downloaded from CalderaDock. You might be interested in reading: How to download a profile from CalderaDock?
