And... the only reason I got a working printer is I made myself a member of the
'sys' group otherwise creation of /etc/cups/printer.conf would have failed due
to lack of permission. Since I was a member of the sys group, permission for
cups operation was satisfied, however, apparently printer driver generation with
the 'foomatic-db-generation' package uses another scheme prompting the error.
