Recently, in the Concorde Room Board Room, I went to print 2 pages from an online OU course I am doing and somehow it started to print the entire 150 page course book. I tried everything to clear the print queue, turned off the printer etc but in the end they had to get a technician to come and clear it. It probably would have been quicker to just let the printer run its course!
Luckily there are two printers in the Board Room and the other people there could see I didn't mean such a large print run.
Of course while dealing with this I managed to continue to consume copious amounts of expensive champagne while attempting to save BA £1.50 in printer consumables
