The OS/2 port of CUPS has several required components.  For simplicity, these are now separate downloads as each can be updated independently, and the previous all in one packages seemed to create confusion.

Requirements:
[http://www.cups.org CUPS] - OS/2 binary from http://download.smedley.info/cups-1.3.9-os2-20090316.zip 

[http://pages.cs.wisc.edu/~ghost Ghostscript] - OS/2 binary from http://www.smedley.info/os2ports/index.php?page=ghostscript

Depending on your printer, you most likely need one of the following:
[http://gutenprint.sourceforge.net Gutenprint] - OS/2 binary from http://download.smedley.info/gutenprint-5.2.3-os2-20081226.zip - list of supported printers is at http://gutenprint.sourceforge.net/p_Supported_Printers.php

[http://splix.ap2c.org Splix] - OS/2 port of v1.1.1 from http://download.smedley.info/splix-1.1.1-os2-20081226.zip (needs [http://smedley.info/gcc432.zip GCC432.DLL] - list of supported printers at http://splix.ap2c.org/ - all Samsung or Xerox printers

eCups.drv: A modified version of IBM's pscript.drv with improvements to compatibility with CUPS.  New version: http://download.smedley.info/ecups-20081228.zip - includes 650 or so printers from Gutenprint 5.2.3 and all printers from Splix v1.1.1

Installation notes:
CUPS and Gutenprint/Splix need to be extracted into the root directory of the SAME drive - some Gutenprint/Splix files need to be installed into the CUPS directories.

Ghostscript also needs to be installed.  The current CUPS build expects to find gsos2.exe in \gs\gs8.63\bin\gsos2.exe - ie on the same drive as CUPS.  If this isn't the location of Ghostscript, you can edit \cups\lib\cups\filter\pstoraster and edit the PREFIX which points to the Ghostscript location.  gs863os2.zip contains only the directory gs8.63 for compatability with GSView so take care when extracting.

Refer to the CUPS [wiki:HowTo] for more details on how to use CUPS, particularly the stuff on setting up the port driver and importing PPD files into pscript.drv
