Hi, I am Dave, I will help you with this.
Click your Start Button, then just type cmd and on the resulting list, right click 'Command Prompt' and select 'Run as administrator'.
Run the following commands and press enter after each one:
net stop spooler
del %systemroot%\System32\spool\printers\* /Q
net start spooler
Close Command Prompt.
The print queue should then be clear.
