[cups.general] Incorrect default printer

[Till Kamppeter]

There is also /etc/cups/lpoptions which has priority against
/etc/cups/printers.conf. To change settings in /etc/cups/lpoptions, use
the lpoptions command as root. the lpoptions command as user sets
personal defaults in the ~/.lpoptions file.
