Simple Printing from the browser
(Method 1) Add some Javascript to an HTML button

(Method 2) Add some Javascript to a Button from the server side:
Button2.Attributes.Add("onclick", "window.print(); return false;")

Note that Method 2 can also be used for other things like a Confirm dialog for a postback

Button1.Attributes.Add("onclick", "return confirm('Are you sure?')")

Dynamically Enabling Page Caching, Based on DEBUG Mode
Because of the headaches that page caching can cause when you are in development mode, you may want to dynamically enable or disable page caching based on something like a compiler constant:

#If DEBUG Then
    lblStatus.Text = "*NOT* using output caching (debug mode)"
#Else
    Response.Cache.SetExpires(Date.Now.AddMinutes(20))
    lblStatus.Text = "using output caching (Production mode)"
#End If
