You cannot delete the print job by using the normal printer panel. A reboot does not solve the problem.
Windows uses the spooler service to prepare printer jobs. Sometimes these can hang and cause problems. This makes it necessary to delete the spooled files in the directory "C:\WINDOWS\system32\spool\PRINTERS"
(You can better refer to it with %systemroot%\system32\spool\printers)
Here you will find the spooled jobs. To delete such a job you need to stop the spooler by:
net stop spooler
Now you can navigate to the directory with your explorer or with a command line and delete the tmp files.
To start the spooler again, you use the command:
net start spooler
Now you can try to print again.
