   "If printer instances are defined in ~/.lpoptions, kprinter sees them, 
    but the `lpoptions` command adds them always to ~/.cups/lpoptions."

KDEPrint is guilty of ab-using a few "private" interfaces of the CUPS API. When CUPS moved from 1.1.x to 1.2.0, some of these interfaces changed, and KDEPrint does now no longer understand some little details of CUPS' doing.

One of the things that changed is the location of the file to store "lpoptions".

You can fix this on your side locally, like so:


  * copy the contents of ~/.loptions to ~/.cups/lpoptions:
 
    mkdir ~/.cups   # in case this directory is not yet there
    cat ~/.loptions >> ~/.cups/lpoptions   # in case the file already exists

 
  * remove ~/.loptions and create a symlink pointing from ~/.loptions to ~/.cups/lpoptions:

    rm ~/.loptions 
    ln -s ~/.cups/lpoptions ~/.loptions


The symlink will ensure that KDEPrint will use the right file for CUPS even if it only knows to access the "old" filename.

wrote a new $summary; old one was "kprinter does not recognize CUPS printer instances and their options (~/.cups/lpoptions)".
