Troubleshooting printing

There is no printing server currently on CLON Cluster, every machine sends job directly to printers.

WAS: To RESET printing queue use "lpc" command on CLON01 (as root):

# lpc
lpc> clean clonhp
       removed clonhp-789
lpc> status
clonhp:
       queueing is enabled
       printing is enabled
       no entries
