From Robert Krawitz:
Gimp-Print is a package of high quality printer drivers for Linux, BSD, Solaris, IRIX, and other UNIX-alike operating systems. The package supports almost 300 printers made by Canon, Epson, Hewlett-Packard, Lexmark, and true compatibles and includes: native CUPS driver, providing simple configuration and operation with CUPS; native Ghostscript driver that can be compiled into Ghostscript; new, IJS-based Ghostscript driver that greatly simplifies installation for Ghostscript versions 6.53 and newer. Gimp-Print supports Foomatic for simplified configuration with all common printing systems. Extensive output adjustments offer a tremendous range of adjustment to match color, brightness, and contrast. A wide range of printer output resolutions is supported, permitting you to trade off printing speed against output quality. 16-bit precision produces virtually stepless output. Bundled utilities perform basic maintenance for Epson and Lexmark printers. Extensive documentation for both users and developers is included. Gimp-Print 4.3.18 is the latest Mac OS X release in the 4.3.x developmental line.
