One print queue was having backlog of hundreds of print jobs , disable and enable print queue.
/usr/sbin/cupsenable <printer_name>
Verify it using
#lpstat -a printername
printername accepting requests since Fri 11 Sep 2015 03:13:13 PM PDT

To check the queue
lpstat -o printername
--------------
To manage it using non-root user , verify whether user in groups





#groups  (would show the groups that your user is in)
To see if lpadmin is listed. If not:
sudo adduser <your-user-name> lpadmin

Then, to gain access to the new group without logging out and logging in again:
newgrp lpadmin

==>To check queue use
lpq -P printername
==>To cancel the jobs
If you have a list of duplicate pending jobs, be sure to delete the duplicates to avoid having your print job come out multiple times.To delete a queued job, type the following (n should be the number in the Job column of the lpq output):

cancel <n>

/usr/sbin/cupsenable printername

/usr/bin/enable (Printer Name)
service cups restart
service cups stop
