Hand-edited /etc/termcap:
root@notlookedfor:/home/hendrik# cat /etc/printcap
HL3170CDW:\
:mx=0:\
:sd=/var/spool/lpd/hl3170cdw:\
:sh:\
:lp=515@172.25.1.122:\
:if=/opt/brother/Printers/hl3170cdw/lpd/filterhl3170cdw:
root@notlookedfor:/home/hendrik#
Now I get
hendrik@notlookedfor:~$ lpr -h -PHL3170CDW
Documents/math/Librationism=1407.3877v3.ps
lpr: cannot open /var/spool/lpd/hl3170cdw/.seq: Permission denied
hendrik@notlookedfor:~$
This happens even if I run as root:
root@notlookedfor:/home/hendrik# lpr -h -PHL3170CDW
Documents/math/Librationism=1407.3877v3.ps
lpr: cannot open /var/spool/lpd/hl3170cdw/.seq: Permission denied
root@notlookedfor:/home/hendrik#
That directory is owned by the lp daemon:
oot@notlookedfor:/home/hendrik# ls -al /var/spool/lpd/hl3170cdwtotal 8
drwx------ 2 daemon lp 4096 Oct 5 14:40 .
drwxr-xr-x 5 root root 4096 Oct 19 09:02 ..
-rw------- 1 daemon lp 0 Oct 5 14:32 acct
-rw------- 1 daemon lp 0 Oct 5 14:32 log
-rw------- 1 daemon lp 0 Oct 5 14:32 status
-rw------- 1 daemon lp 0 Oct 5 14:32 status.pr
root@notlookedfor:/home/hendrik#
and it contains no .seq file. Preumably that fle would be created as needed.
And presumably the permissions are checked in some way that can exclude root.
