From the T-Rip site:
T-RIP is the big brother to Scott Fresener’s original FastRIP. FastRIP was the defacto standard in RIP software for garment printers for many years. It was the first affordable industry specific RIP on the market. In mid-2009 FastRIP was upgraded and became T-RIP. The problem is that FastRIP is now at least five years old and it won’t work on most of the newer computer operating systems including 64-bit computers. And, it does not have drivers for the newer Epson printers like the 1430, 4900, Workforce series and others.
