[K12OSN] About printing

[John P. Conlon]

Our typing lab teacher would like to be able to hold documents sent to 
print in the print que until she can check them for extra blank pages.  
To accomplish this she wants to be able to open the documents in the 
print que right there in the print que while logged in as either herself 
or as root.  Is this possible and if so how do I set it up for her.  
This particular teacher is an appliance operator not a computer manipulator.
