When I give command 'lpr filename', a file 'nitin' gets created in /tmp but of size 0. My error log file is as shown below -

hello Michael,

I checked the /var/log/messages - but did not find
any error message there.
Also checked rights of the directories - /var , /var/spool, and
/var/spool/cups. /var & /var/spool are owned by root user, root group.
/var/spool/cups is owned by root user, lp group. Inside the /var/spool/cups directory, there were no d* files, instead c* files.
and a tmp directory. All these files were owned by root user, sys group.
The tmp folder was owned by root user, lp group.
I am trying to understand this - but the program which tries
to access these files is lpr, right? which does not have rights
to access these directories and the files in them.
Is this what is happening, so that I need to change access rights of
these folders and then they would be accessible by this user.
Please clarify if my guess about the user and these directories
is correct.

Thank you so much for your interest in my problem.
Regards,
Nitin
