this is how to install it on a 64bit system

first: connect printer/scanner to the router (use the menu on the device, start in menu, connect to WLAN and enter key which is in my case for a WEP encrypted key)
then (As I'm a dpkg users)
I install the standard c library for 32bit applications; ia32-libs(Ubuntu) use synaptic fr=or this
create some folders, if it is required
mkdir /usr/lib/cups
mkdir /usr/lib/cups/filter
create /usr/share/cups/model if it does not exist
install the drivers using --force-all option.
copy brlpdwrapperdcp585cw file under /usr/lib/cups/filter/ to /usr/lib64/cups/filter/
copy libbrXXXX files under /usr/lib/ to /usr/lib32/ if /usr/lib32 exists.
