You might try restarting the print spooler service on your computer. If the printer itself has a hard drive you might physically unplug the printer from the wall or depending on make and model go into the print cue and manually delete it. Most printers have their own status and configuration website now too. Use your browser to go to the IP address of the printer, this is assuming it is a network printer. If it is USB or parallel then try restarting the print spooler service on your computer as I said above.
