When an AccuRIP Driver is shared from a computer to another and when printing from an illustration graphics program it does not load the PPD file (PostScript Printer Description) the answer is usually that the wrong driver was shared.
Most operating systems (Mac to Mac) or (Windows to Windows) depending on the versions of the operating systems will automatically load print drivers and PPDs. As noted the wrong (non PostScript) driver was selected or you need to manually load them then add a shared driver. This is possible with a printer that is setup using a USB conection on a PC since there are two drivers, the AccuRIP print driver and the Epson printer driver. Verify that you shared the AccuRIP to Epson print driver. If you did not give your shared printer a custom name, the print driver must be AccuRIP to Epson. If it is another name, especially if it has the words Epson Stylus in the driver name, it is a good chance you shared the wrong print driver.
