I'm not a Mac user so I can't give you any troubleshooting suggestions. But I can recommend that you visit the Epson website and download the latest printer driver for your printer and read all the material there on using the R2880 with the specific Mac OS version you are using. There have been numerous issues with the Epson drivers and the myriad of Mac OS'es. So much for the Macs being trouble free. I run five Epson printers and an Epson scanner on a Win 7 box with zero issues.
