The Samsung ML-1210 printer works perfect under Win32, under linux (not so good), but not under Win64. This tool is not a complete driver, even presently not a 64-bit, but it allows to print graphic files. It uses code from ghostscript 5.10 for linux.
GnuWin64 provides Win64-versions (x64) of GNU or similar open source tools. The ports are native ports, that is they rely only on libraries provided with 64-bit Microsoft Windows operating system for the AMD64 and Intel64 (EM64T) architecture.
