I used to work in a University computer lab. Every year, the final year students had to do a project that would take one year, and write a report that needed to be between 8 and 12 thousand words on it. As a computer science student myself, I was required to design a computer system or application, and write an 8,000 word report on the development... This project needed to be handed in at the courseworks office, with a printed and bound copy of the report that could also contain other media (such as a disc containing the the application) by 4pm on deadline day.
Of course, despite the lecturers continually reminding us to get as much as possible ready early, including printing the report, almost no one did. The practical result of this was that by 8am on deadline, even though we had at least one Laserjet 5si (Enterprise level network printer), the queue for each printer was already at least 3-4 hours. Of course, we technicians did get shouted at because our printers weren't fast enough, but the standard response was "You were warned, you should have printed earlier", even from Uni management.
The computers and printers were networked using a Novell Netware network. I'm not entirely sure what software used to manage the print jobs, but I * think* was Pcounter.
Whatever the software was, it gave the technicians in charge of each lab the ability to re-arrange the jobs on each queue manually. One day, my colleague, who I liked, but was arguably a BOFH and could be slightly scary if you didn't know him, decided he needed to print some stuff out urgently. That something turned out to be the Netware manuals. 2,000 pages of them. So, he found a PDF, printed it and bumped his own job up to the top of the queue. Thankfully, all our 5si's had several standard capacity paper drawers (one ream each) and a high capacity paper cabinet that could take a box of paper.
I don't remember what happened, but I suspect there were a lot of complaints.
I have to admit, I don't miss those days. Being the junior tech in the lab, I essentially spent all day (on that day of each academic year anyway) making sure all the printers were kept fed with paper, toner, maintence kits and ink (as appropriate), also making sure there were no paper jams. Babysitting the printers all day, to keep them running was incredibly boring.
