A preview of CUPS 1.2.6 (www.cups.org) + ESP Ghostscript 8.15.3 (http://www.cups.org/espgs/) + Gutenprint 5.0.0 (http://gimp-print.sourceforge.net/) is now available at http://download.smedley.info/cups-1.2.6-os2-a1.zip
Some notes on the release are contained in /cups/readme.os2 after unzipping.
I'd be interested in any feedback. Currently a port driver isn't included, but Bart is working on this (http://svn.netlabs.org/ecups/).
Cheers,
Paul.
