string

So in assembly I declare the following String:

Sample db "This is a sample string",0

In GDB I type "p Sample" (without quotes) and it spits out 0x73696854. I want the actual String to print out. So I tried "printf "%s", Sample" (again, without quotes) and it spits out "Cannot access memory at address 0x73696854."

Short version: How do I print a string in GDB?
