CUPS unable to automatically locate printer09 Jan 2016
After an update sometime ago, cups started to fail when trying to print to printers that were automatically detected. The printers address would show up as
When trying to print to such a printer, cups would give the following error:
Unable to locate printer 'BRWXXXXXX.local'
If you have avahi running, then you can run
to list all the network printers. This would show, for example
network ipp network ipps network socket file cups-pdf:/ direct hp network lpd network http network https network smb direct hpfax network dnssd://Brother%20DCP-L2540DW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-xxxx-xxxxxxxxx network lpd://BRW1008B19C71E2/BINARY_P1
The problem is that the correct libraries were not installed; see this askubuntu page. It tells you that you need to install the nss-mnds library. This is some sort of dns service that is necessary for cups to function. Once you install it using
pacman -S nss-mdns
Edit the file
so that the hosts line contains.
hosts: files mdns_minimal dns mdns
