Whether you are printing to a printer in your classroom or to the Toshiba Copier, sometimes it just doesn't print.
It acts like it has sent it, but when you get to the printer, it isn't there.
There is a good possibility that your computer needs to be restarted. There are "services" that run in the background on your computer that you don't realize are there. One of these is called the "Print Spooler." The Print Spooler is what pushes the print job to the printer. This service will lock up sometimes on its own if the computer has been running for several days without being restarted or shut down.
If this is happening to you, try restarting.
