Epson Media Installer allows you to add Epson and non-Epson media settings for paper types not already in your product's control panel and printer driver. Epson Media Installer downloads selected paper type settings from an online server and then registers those settings to your printer and printer driver.
You can use Epson Media Installer to download settings for a paper type or use the settings as a starting point for a similar paper and then edit them, as needed.
