As you might expect, reference staff spends a lot of time answering "how do I print" questions. But software and hardware glitches aside, sometimes the PEBCAK errors can be entertaining. To wit, I helped these two patrons on the same day:
A teenage patron was printing out a webpage. I showed him how to print, and then walked with him to the print station. When we got there, we found someone had left a quarter and two dimes on top of the pay box. People sometimes do this to be nice to the next person, or they leave it there if they find change in the machine.
I could see the kid eyeing it, and finally he asked, "did someone leave those coins there?" I said, "yes, you can use it to print your job if you like." "Or I can take it," he replied, smiled conspiratorially, and scooped it up and put it in his pocket.
Then he proceeds to take out his wallet, remove enough coins to pay for his print job, and insert them in the pay box.
Later a very stylishly-dressed woman needed help printing. I showed her that her job would cost fifteen cents, so she digs in her coin purse for coins. First she pulls out a dime and a Canadian nickel, which she puts on a table and then slides apart. Next she fishes out a few pennies and a Euro. She reaches in again and pulls out what looked like an old Chinese coin with a hole in the middle and an American nickel.
Wile inserting the fifteen cents, she says in a tone obviously meant to impress me, "whew, all this foreign money - I suppose I should stop traveling the world so much."
But that's all fine - as long as the printer prints when it's supposed to and doesn't take peoples' money, I'm happy.
