Apsfilter handbook is available for developement and -stable version. You find it in the apsfilter sources and on the webserver. Currently both versions are the same, since all from apsfilter-current has been merged into the new apsfilter version 6.1.0. January 2001 Michael Lossin was so kind starting to write the apsfilter handbook in html. Samba remote printing was broken in 6.0.0, because the variable containing the windows password has been named incorrect.
Patches are available as usual from the download page.
After a long testing period I'm proud to present apsfilter V 6.0. Many thanks to the team, especially to Michael Lossin. Only with his continous help V 6.0 became true and is as mature as it is now. Many useful features have been coded by Michael, i.e. pseudo duplex printing to mention only one. Also a big thanks to Matej Vela who initially started apsfilters code cleanup which ended in a complete great rewrite.
