How to decrease CPU Usage?

I am running a late 2011 Macbook Pro 13 inch with a 512 SSD that I installed myself over a year ago. My fan is running constantly and I have tried the easy things like closing all running programs and applications and even taken the back off and vacuumed any and all dust out which there was very little. I downloaded istat like I saw on several other threads and it revealed my CPU usage to be 93% user and only 7% System. So, I assume that identified why my fan is running constantly but now what? What should my User Usage be and how do I decrease it?

MacBook Pro, OS X Yosemite (10.10)

As per your duplicate post.

Use Activity monitor to determine what App(s) are using such high percentages of the CPU.

Use Activity Monitor on your Mac - Apple Support

Edit

CPU usage 93% User

First, I apologize for the duplicate post.

Second, Thank you stedman1! I followed the directions to see what was using the most CPU usage. It was com.hp.devicemodel.TranportProxy,

I searched the web for that and came up with a recent HP printer update that was causing it and instructions to make it stop.

Go to Finder >> Go to Folder
Type: /Library/Printers
You will find a printer list on that folder.

Delete hp folder (but don't empty trash!), enter your admin password
Restart your OS X.
Do the check up steps above through Activity Monitor, whether process name com.hp.devicemodel.TranportProxy still there? it should not be there
Go to Trash, right click hp folder on trash and choose Put Back. Your hp folder will back to its previous place.

Now I am only using about 7% of CPU
