If you have recently installed the latest Epson Printer Drivers Update via Apple's Software Update tool or from the Apple Corp. website, then you may need to refresh your Epson printer driver installation. The latest printer driver update provides updated driver software to many Epson printer models.
If you are receiving the message "Error: /Library/Printers/EPSON/InkjetPrinter2/Filter/rastertoescpll.app/Contents/MacOS/rastertoescpll" or "'Filter' failed" when attempting to print we recommend trying the below troubleshooting after referring to the below article:
If you are yet to install the Epson Printer Drivers Update and instead want some advice on whether you should update the drivers, please read our recommendations in section "I haven't updated my Mac yet but want some advice. Should I install all the latest printer driver updates?" (below).
If you have found that you can no longer print to your Epson printer, we recommend that you follow the steps below.
This removes all added printer drivers. For more information on the Reset Printing System feature, click here to view Apple's support article.
If printing fails after following the process above, or only the Gutenprint driver is added when you attempt to add the printer, you could remove the Gutenprint driver folder from your Mac or uninstall the Gutenprint drivers using the Gutenprint Uninstaller, available at http://gimp-print.sourceforge.net/MacOSX.php. Reset the printing system and restart the Macintosh before re-adding the printer again. If you want to reinstall the Gutenprint driver package or any other official Mac OS X printer driver package at any time, please use the downloads available at Apple's support website.
If you are yet to install the Epson Printer Drivers Update then whilst some printer software updates are provided, we recommend that you consider if it is required - for example you do not need to install the updated printer driver package if your printer is already supported and no updated driver software is provided and if you do not have any other Epson printers that require support. If your printer was released after the release of of your version of macOS, then the driver is on the supplied Epson software CD-ROM.
For information on which Epson printer models benefit from the update, please refer to the latest list available on Apple's website: http://support.apple.com/kb/HT3669.
