(Redirected) Insufficient Hard Drive Space

I have Venue Pro 8. I use it only to print coupons. I have no apps downloaded. I went to connect a new printer and it gives me the message"insufficient hard drive space" I am not very computer literate and have no idea how to free up disk space. I cannot even figure out why I would have no space. I am good at following directions so if someone would try to help me I would be very appreciate.TIA
