I am using a HP printer. The model number is HP PSC 1410. It is configured on the lan network and it is shared. All workstations on the network can access the same. But somehow there is a problem with printer job. I found in morning that number of print job are stucked on the same. I tried to delete them but it is not going and now no one is able to print. What can be cause of the same. The printer is new and configuration is done by a network guy who is not available for 2 days. How can I fix this problem.
