You mean "if I print a file as root, using the 'lp' command" ?

Well, the permissions should be '-rw-r-----', not '-rw-------".
The lines should read s.th. like
-rw-r----- 1 root lp 223967 Oct 17 02:22 d88264-001
-rw-r----- 1 root lp 859 Oct 17 02:22 c88264
or, in case your system uses "Group sys" in cupsd.conf:
-rw-r----- 1 root sys 223967 Oct 17 02:22 d88264-001
-rw-r----- 1 root sys 859 Oct 17 02:22 c88264

Well, by *default* your filters and backends will run as 'lp', while
cupsd itself runs as 'root'.
>From what your above permissions for the c00001 file tells, this is
somehow different for you. *IF* in your case the filters run as root,
it could work.
