[FreeNX-kNX] Client-side CUPS printing

At least in v.2.1 client, this was buggy.

Seems perfect.

Okay.

This seems like !M did not update the client to support CUPS v1.2.

You can use a wrapper script, which you point the NXClient to instead of /usr/sbin/cupsd.

See svn://svn.berlios.de/freenx/nx-utils/nxcupsd-wrapper

or

http://svn.berlios.de/svnroot/repos/freenx/nx-utils/nxcupsd-wrapper/

There is also a README explaining what I wrote.

Note: Using the wrapper you can also automatically download the right driver by setting ENABLE_CUPS_SEAMLESS="1" in node.conf, which I would only try once the general setup is working correctly.
