[Nix-dev] printing on nix

[Nawal Husnoo]

Hi,

I've got the default.nix below, and I run it using nix-shell. I opened
firefox, and went to 127.0.0.1:631 and added a printer, and selected the
ppd file from /opt/share/ppd/canonmp250.ppd.

Unfortunately, when I try to print a test page I get the error message:

Idle - "File
"/nix/store/wy6c4mlp6zhjj4j3cjwrhwfi4ba9bxab-cups-progs/lib/cups/filter/pstocanonij"
not available: No such file or directory"

The file lives at /opt/lib/cups/filter/pstocanonij.

How do I override cups path in nix?

thanks,

Nawal.
